Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business and Basis of Presentation	Nature of Business and Basis of Presentation Organization Charah Solutions, Inc. (together with its subsidiaries, “Charah Solutions,” the “Company,” “we,” “us” or “our”) was formed as a Delaware corporation in January 2018 and did not conduct any material business operations prior to the reorganization transactions described below other than certain activities related to the initial public offering (the “IPO”), which was completed on June 18, 2018. Charah Solutions is a holding company, the sole material assets of which consist of membership interests in Charah Management LLC, a Delaware limited liability company (“Charah Management”), and Allied Power Holdings, LLC, a Delaware limited liability company (“Allied Power Holdings”). Through the Company’s ownership of Charah Management and Allied Power Holdings, the Company owns the outstanding equity interests in Charah, LLC, a Kentucky limited liability company (“Charah”), and Allied Power Management, LLC, a Delaware limited liability company (“Allied”), the subsidiaries through which Charah Solutions operates its businesses. The historical financial data presented herein as of September 30, 2019 and December 31, 2018 and for the periods after the June 18, 2018 corporate reorganization described below is that of Charah and Allied on a consolidated basis, and is on a combined basis for the periods prior to the June 18, 2018 corporate reorganization. Corporate Reorganization On June 18, 2018, pursuant to the terms of the reorganization transactions completed in connection with the IPO, (i) (a) Charah Holdings LP, a Delaware limited partnership (“Charah Holdings”) owned by Bernhard Capital Partners Management, LP and certain related affiliates (“BCP”), contributed all of its interests in Charah Management and Allied Power Holdings to the Company in exchange for 17,514,745 shares of common stock, (b) CEP Holdings, Inc., a Delaware corporation owned by Charles E. Price and certain affiliates, contributed all of its interests in Charah Management and Allied Power Holdings to the Company in exchange for 4,605,465 shares of common stock, (c) Charah Management Holdings LLC, a Delaware limited liability company (“Charah Management Holdings”), contributed all of its interests in Charah Management and Allied Power Holdings to the Company in exchange for 907,113 shares of common stock and (d) Allied Management Holdings, LLC, a Delaware limited liability company (“Allied Management Holdings”), contributed all of its interests in Charah Management and Allied Power Holdings to the Company in exchange for 409,075 shares of common stock; (ii) each of Charah Management Holdings and Allied Management Holdings distributed the shares of common stock received by them pursuant to clause (i) above to their respective members in accordance with the respective terms of their limited liability company agreements; and (iii) Charah Holdings distributed a portion of the shares of common stock it received in clause (i) above to certain direct and indirect blocker entities which ultimately merged into the Company, with the Company surviving, and affiliates of BCP received shares of common stock as consideration in the mergers. Description of Business Operations The Company is a leading provider of mission-critical environmental and maintenance services to the power generation industry, enabling our customers to address challenges related to the remediation of ash ponds and landfills at open and closed power plant sites while continuously operating and providing necessary electric power to communities nationwide. We offer a suite of coal ash management and recycling, environmental remediation and outage maintenance services. The Company also designs and implements solutions for complex environmental projects (such as coal ash pond closures) and facilitates coal ash recycling through byproduct sales and other beneficial use services. The Company has corporate offices in Kentucky, Louisiana and North Carolina, and principally operates in the eastern and mid-central United States. Under the Jumpstart Our Business Startups Act (the “JOBS Act”), the Company meets the definition of an “emerging growth company,” which allows the Company to have an extended transition period for complying with new or revised financial accounting standards pursuant to Section 107(b) of the JOBS Act. The Company intends to take advantage of all of the reduced reporting requirements and exemptions, including the longer phase-in periods for the adoption of new or revised financial accounting standards under Section 107 of the JOBS Act until the Company is no longer an emerging growth company. Among other things, we are not required to provide an auditor attestation report on the assessment of the internal control over financial reporting under Section 404(b) of the Sarbanes-Oxley Act of 2002 and our disclosure obligations regarding executive compensation may be reduced. We may take advantage of these provisions until the last day of our fiscal year following the fifth anniversary of the IPO, or December 31, 2023. However, if certain events occur prior to the end of such five-year period, including if we become a “large accelerated filer,” our annual gross revenue exceeds $1.07 billion or we issue more than $1.0 billion of non-convertible debt in any three-year period, we will cease to be an emerging growth company prior to the end of such five-year period. Basis for Presentation The Company’s fiscal year ends December 31. The accompanying unaudited condensed consolidated and combined financial statements include the assets, liabilities, stockholders’ and members’ equity, and results of operations of the Company and its consolidated and combined subsidiaries. Intercompany transactions and balances have been eliminated in consolidation. The accompanying unaudited condensed consolidated and combined financial statements have been prepared in accordance with rules and regulations of the Securities and Exchange Commission for quarterly reports on Form 10-Q. In the opinion of management, all adjustments considered necessary for a fair presentation have been included, which consist of normal recurring adjustments. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted. The accompanying unaudited condensed consolidated and combined financial statements should be read in conjunction with the audited consolidated and combined financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2018. Unaudited Pro Forma Income Information The unaudited pro forma income information gives effect to the corporate reorganization that occurred in connection with the closing of the IPO and the resulting legal entity of Charah Solutions, which is incorporated as a “C” corporation. Prior to the corporate reorganization, the holding companies for Charah and Allied were limited liability companies and generally not subject to income taxes. The pro forma net income, therefore, includes an adjustment for income tax expense as if the holding companies for Charah and Allied had been “C” corporations for all periods presented at an assumed combined federal, state and local effective income tax rate of 25% for the periods from January 1, 2018 through June 17, 2018, plus the actual tax expense for the periods after June 18, 2018. These rates approximate the calculated statutory tax rate for each period. Related Party Transactions The Company rents their corporate office, housing at work sites and a condo from Price Real Estate, LLC (“Price Real Estate”), an entity owned by a stockholder of the Company. The lease for the corporate office is a triple net lease through May 31, 2020, requiring monthly payments of $39 as of September 30, 2019 , increasing by the consumer price index each year on June 1. Other property is rented on a month-to-month basis. Rental expense was $117 and $116 during the three months ended September 30, 2019 and 2018 , respectively, and $349 and $342 during the nine months ended September 30, 2019 and 2018 , respectively. The Company had no receivables outstanding from Price Real Estate and no payables due to Price Real Estate as of September 30, 2019 and December 31, 2018 . Brown & Root Industrial Services, LLC (“B&R”), an entity 50% owned by BCP, our majority stockholder, provided subcontracted construction services at one of our remediation and compliance service sites. Expenses to B&R were $0 and $4,125 during the three months ended September 30, 2019 and 2018 , respectively, and $1,311 and $12,750 during the nine months ended September 30, 2019 and 2018 , respectively. The Company had no receivables outstanding from B&R as of September 30, 2019 and December 31, 2018 . The Company had payables, net of credit memos, due to B&R of $1,419 and $4,919 as of September 30, 2019 and December 31, 2018 , respectively.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) , requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The core principle of Accounting Standards Codification (“ASC”) Topic 606 is to recognize revenue when a customer obtains control of a good or service, in an amount that reflects the consideration to which an entity is expected to be entitled for those goods or services. Additionally, this ASU requires enhanced qualitative and quantitative disclosures regarding customer contracts. This ASU will replace most existing revenue recognition guidance in GAAP when it becomes effective and permits the use of either a full retrospective transition method or a modified retrospective with cumulative effect transition method. To assess the impact of this ASU, we utilized internal resources to lead the implementation effort and supplemented them with external resources. The Company’s adoption activities were performed over three phases: (i) assessment, (ii) design and (iii) implementation using a cross-functional team that included accounting, operational and information technology personnel. Based on our work to date, we believe we have identified all material contract types, revenue and costs that may be impacted by implementing ASC Topic 606. Generally, the Company believes the majority of its contracts will have similar performance obligations under ASC Topic 606 as compared with the units of account previously identified. We have identified certain contracts where the timing of revenue recognition will change under ASC Topic 606. Prior to the adoption of ASC Topic 606, revenue recorded for certain contracts with fluctuating rates per unit matched the amount that was billed to the customer. In accordance with ASC Topic 606, for contracts with fluctuating rates per unit that are not directly related to changes in the Company’s effort to perform under the contract, the Company will recognize revenue based on the stand-alone selling price per unit, calculated as the average rate per unit over the term of those contractual rates. This accounting treatment will at times create a contract asset or liability for the difference between the revenue recognized and the amount billable/billed to the customer. As a calendar year-end emerging growth company that has elected to take advantage of the extended transition period for complying with new or revised financial accounting standards, we are required to adopt the new revenue standard for annual periods beginning on January 1, 2019, and for interim periods within annual periods beginning on January 1, 2020. Accordingly, the interim periods within the year ending December 31, 2019 will be reported under the existing revenue standard, ASC Topic 605, while the annual period for the year ending December 31, 2019 will be reported under ASC Topic 606. For the annual period for the year ending December 31, 2019, we will apply the requirements of ASC Topic 606 to all contracts using the modified retrospective with cumulative effect transition method. Accordingly, we will recognize the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of retained earnings for the year ending December 31, 2019. The comparative information will not be restated and will continue to be reported under the accounting standards in effect for the comparative periods. Based upon our assessment of the impact of the adoption of ASC Topic 606, we estimate a decrease of approximately $300 to the opening balance of retained earnings as of January 1, 2019, with an associated decrease in the contract asset balance “costs and estimated earnings in excess of billings.” In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , requiring all leases to be recognized on the balance sheet as a right-of-use asset and a lease liability, unless the lease is a short-term lease (generally a lease with a term of 12 months or less). At the commencement date of the lease, the Company will recognize: (i) a lease liability for the Company’s obligation to make payments under the lease agreement, measured on a discounted basis; and (ii) a right-of-use asset that represents the Company’s right to use, or control the use of, the specified asset for the lease term. This ASU originally required recognition and measurement of leases at the beginning of the earliest period presented using a modified retrospective transition method. In July 2018, the FASB issued ASU No. 2018-11, which provided an additional (and optional) transition method that permits application of this ASU at the adoption date with recognition of a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. In October 2019, the FASB delayed the effective date of this ASU, extending the effective date for non-public business entities and making the ASU effective for the Company for the fiscal year ending December 31, 2021, and interim periods within the fiscal year ending December 31, 2022, with early adoption permitted. The Company has not yet selected a transition method and is currently evaluating the effect that the adoption of this ASU will have on its consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments — Credit Losses (Topic 326) — Measurement of Credit Losses on Financial Instruments , which introduces a new model for recognizing credit losses on financial instruments based on an estimate of current expected credit losses. The new model will apply to: (1) loans, accounts receivable, trade receivables, and other financial assets measured at amortized cost, (2) loan commitments and certain other off-balance sheet credit exposures, (3) debt securities and other financial assets measured at fair value through other comprehensive income, and (4) beneficial interests in securitized financial assets. The amendments contained in this ASU will be applied through a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. In November 2018, the FASB issued ASU No. 2018-19, which amended the effective date of ASU No. 2016-13 and clarified that receivables arising from operating leases are not within the scope of Subtopic 326-20. In October 2019, the FASB delayed the effective date of this ASU, extending the effective date for non-public business entities and making the ASU effective for the Company for the fiscal year ending December 31, 2023, and interim periods therein, with early adoption permitted. The Company is currently evaluating the effect that the adoption of this ASU will have on its consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments . This ASU addresses specific cash flow issues, including debt prepayment or debt extinguishment costs, contingent consideration payments made after a business combination, and proceeds from the settlement of insurance claims. This ASU is effective for the Company for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. The Company is currently evaluating the effect that the adoption of this ASU will have on its consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230) . This ASU requires that a statement of cash flows explains the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Upon adopting this ASU, amounts generally described as restricted cash or restricted cash equivalents will be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the consolidated statement of cash flows. ASU No. 2016-18 is effective for the Company for interim and annual periods beginning after December 15, 2018. The Company adopted ASU No. 2016-18 effective January 1, 2019, with retrospective application to our consolidated and combined statements of cash flows so that the consolidated and combined statements of cash flows present a reconciliation of the changes in cash and cash equivalents and restricted cash. The adoption of this ASU did not have a material impact on our consolidated financial statements. As a result of this retrospective adoption, the amount of cash and cash equivalents previously presented in the consolidated and combined statements of cash flows increased by $3,358 to reflect the inclusion of restricted cash in the amount reported for changes in cash, cash equivalents and restricted cash as of the beginning and end of the period for the period from January 1, 2017 through January 12, 2017 and as of the beginning of the period for the period from January 13, 2017 through December 31, 2017. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . This ASU simplifies the measurement of goodwill impairment by eliminating the requirement that an entity compute the implied fair value of goodwill based on the fair values of its assets and liabilities to measure impairment. Instead, goodwill impairment will be measured as the difference between the fair value of the reporting unit and the carrying value of the reporting unit. This ASU also clarifies the treatment of the income tax effect of tax-deductible goodwill when measuring goodwill impairment loss. In October 2019, the FASB delayed the effective date for implementation of ASU No.2017-04. The Company will be required to adopt ASU No. 2017-04 for annual and any interim impairment tests for the periods beginning after January 1, 2023. ASU No. 2017-04 must be applied prospectively, with early adoption permitted. The Company is currently evaluating the effect that the adoption of this ASU will have on its consolidated financial statements.

Business Combinations [Abstract]
Business Combination	Business Combination On March 30, 2018, Charah Management completed a transaction with SCB Materials International, Inc. and affiliated entities (“SCB”), a previously unrelated third party, pursuant to which Charah Solutions acquired certain assets and liabilities of SCB for a purchase price of $35,000 , with $20,000 paid at closing and $15,000 to be paid over time in conjunction with certain performance metrics. The contract also contained various mechanisms for a working capital true-up. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations . The allocation of the purchase price for the acquisition was finalized as of March 31, 2019 (as summarized below) with the recognized goodwill allocated to the Environmental Solutions segment. The total amount of goodwill deductible for tax purposes is $2,025 . In November 2018, the $15,000 to be paid over time was reduced by $3,300 . The present value of the future payments using a discount rate of 2.50% was determined to be $11,014 . The Company expects the future payments to occur in 2020 and beyond. The allocation of the purchase price for the acquisition is as follows: Cash acquired $ 17 Net working capital, excluding cash 21,255 Property, plant and equipment 5,300 Trade name intangible assets 694 Customer relationship intangible assets 742 Technology 1,972 Non-compete and other agreements 289 Goodwill 745 Total purchase price $ 31,014 Revenue of $14,890 and $31,463 , respectively, and earnings of $368 and $1,322 , respectively, from the acquired business were included in the unaudited condensed consolidated and combined statements of operations for the three and nine months ended September 30, 2018 . The following unaudited information presents the pro forma consolidated revenue and net loss for the nine months ended September 30, 2018 as if the acquisition had been included in the consolidated results of operations beginning January 1, 2017. Nine Months Ended September 30, 2018 Pro forma revenue $ 554,077 Pro forma net loss attributable to Charah Solutions, Inc. (12,568 ) The above unaudited pro forma results have been calculated by combining the historical results of the Company and the acquired business as if the acquisition had occurred as of the beginning of the fiscal year prior to the acquisition date, and then adjusting the income tax provisions as if they had been calculated based on the consolidated and combined results. The pro forma results include estimates for additional depreciation related to the fair value of property, plant and equipment and intangible asset amortization. The pro forma results reflect the elimination of $589 of direct acquisition costs that were incurred in the nine months ended September 30, 2018 (since for purposes of the pro forma presentation they have been reflected in 2017 instead of in 2018). For all periods presented, historical depreciation and amortization expense of the acquired business was adjusted to reflect the acquisition date fair value amounts of the related tangible and intangible assets. No other material pro forma adjustments were deemed necessary, either to conform the acquisition to the Company’s accounting policies or for any other situation. The pro forma information is not necessarily indicative of the results that would have been achieved had the transactions occurred on the date indicated or that may be achieved in the future.

Goodwill and Intangible Assets	Goodwill and Intangible Assets The Company’s goodwill and intangible assets consist of the following: September 30, 2019 December 31, 2018 Gross Carrying Amount Accumulated Amortization Gross Carrying Amount Accumulated Amortization Definite-lived intangibles: Customer relationships $ 78,942 $ (20,965 ) $ 78,942 $ (15,044 ) Technology 2,003 (301 ) 2,003 (150 ) Non-compete and other agreements 289 (216 ) 289 (109 ) SCB trade name 694 (208 ) 694 (104 ) Rail easement 110 (110 ) 110 (88 ) Total $ 82,038 $ (21,800 ) $ 82,038 $ (15,495 ) Indefinite-lived intangibles: Charah trade name $ 34,330 $ 34,330 Goodwill 74,213 74,213 Total $ 108,543 $ 108,543 Definite-Lived Intangible Assets As of September 30, 2019 and December 31, 2018 , definite-lived intangible assets included customer relationships, technology, non-compete and other agreements, SCB trade name (see Note 3) and a rail easement. These assets are amortized on a straight-line basis over their estimated useful lives as shown in the table below. Amortization expense was $2,094 and $2,135 during the three months ended September 30, 2019 and 2018 , respectively, and $6,305 and $6,232 during the nine months ended September 30, 2019 and 2018 , respectively. Definite-Lived Intangible Asset Useful Life Customer relationships 10 years Technology 10 years Non-compete and other agreements 2 years SCB trade name 5 years Rail easement 2 years Goodwill and Indefinite-Lived Intangible Assets Goodwill represents the excess purchase price over the fair value of the net assets acquired in a business combination. Our goodwill included in the unaudited condensed consolidated balance sheets as of September 30, 2019 and December 31, 2018 was $74,213 . Our intangible assets as of September 30, 2019 and December 31, 2018 include a trade name valued at $ 34,330 that is considered to have an indefinite life. Goodwill and indefinite-lived intangible assets are not amortized, but instead are tested for impairment annually or more often if events or changes in circumstances indicate that the fair value of the asset may have decreased below its carrying value. We perform our impairment test effective October 1st of each year and evaluate for impairment indicators between annual impairment tests. As a result of the Company’s decline in revenue and the operating loss recognized for the six months ended June 30, 2019, the Company performed the first step of the two step analysis for the Environmental Solutions reporting unit during the quarter ended June 30, 2019 and determined that no impairment of goodwill occurred as a result of this triggering event. The Environmental Solutions reporting unit’s fair value, as calculated, was approximately 5.4% greater than its book value as of June 30, 2019. We determined that there were no additional indicators of impairment at September 30, 2019 or September 30, 2018 in the Environmental Solutions or Maintenance and Technical Services reporting units. The valuation used to test goodwill for impairment is dependent upon a number of significant estimates and assumptions, including macroeconomic conditions, growth rates, competitive activities, cost containment, margin expansion and the Company's business plans. We believe these estimates and assumptions are reasonable. However, future changes in the judgments, assumptions and estimates that are used in our impairment testing for goodwill, including discount and tax rates or future cash flow projections, could result in significantly different estimates of the fair values. As a result of these factors and the related cushion as of the date of the previous annual impairment test, goodwill for the Environmental Solutions reporting unit is more susceptible to impairment risk. The most significant assumptions utilized in the determination of the estimated fair value of the Environmental Solutions reporting unit are the net sales and earnings growth rates (including residual growth rates) and the discount rate. The residual growth rate represents the rate at which the reporting unit is expected to grow beyond the shorter-term business planning period. The residual growth rate utilized in our fair value estimate is consistent with the reporting unit operating plans and approximates expected long-term category market growth rates and inflation. The discount rate, which is consistent with a weighted average cost of capital that is likely to be expected by a market participant, is based upon industry required rates of return, including consideration of both debt and equity components of the capital structure. Our discount rate may be impacted by adverse changes in the macroeconomic environment, volatility in the equity and debt markets or other factors. While management can and has implemented strategies to address these events, changes in operating plans or adverse changes in the future could reduce the underlying cash flows used to estimate fair values and could result in a decline in fair value that would trigger future impairment charges of the reporting unit’s goodwill balance. The table below provides a sensitivity analysis for the Environmental Solutions reporting unit, utilizing reasonably possible changes in the assumptions for the shorter-term revenue and residual growth rates and the discount rate, to demonstrate the potential impacts to the estimated fair values. The table below provides, in isolation, the estimated fair value impacts related to (i) a 75 -basis point increase to the discount rate assumption and (ii) a 100 -basis point decrease to our shorter-term revenue and residual growth rates assumptions, both of which would result in impairment charges.

Credit Agreement

Debt Disclosure [Abstract]
Credit Agreement	Credit Agreement On September 21, 2018, we entered into a credit agreement (the “Credit Facility”) by and among us, the lenders party thereto from time to time and Bank of America, as administrative agent (the “Administrative Agent”). The Credit Facility includes: • a revolving loan not to exceed $50,000 (the “Revolving Loan”); • a term loan of $205,000 (the “Closing Date Term Loan”); and • a commitment to loan up to a further $25,000 in term loans, which expires in March 2020 (the “Delayed Draw Commitment” and the term loans funded under such Delayed Draw Commitment, the “Delayed Draw Term Loan”, together with the Closing Date Term Loan, the “Term Loan”). All amounts associated with the Revolving Loan and the Term Loan under the Credit Facility mature in September 2023. The interest rates per annum applicable to the loans under the Credit Facility are based on a fluctuating rate of interest measured by reference to, at our election, either (i) the Eurodollar rate, currently the London Inter-bank Offered Rate (“LIBOR”), or (ii) an alternative base rate. Various margins are added to the interest rate based upon our consolidated net leverage ratio (as defined in the Credit Facility). Customary fees are payable in respect of the Credit Facility and include (i) commitment fees for unused portions of the Credit Facility and (ii) fees on outstanding letters of credit. Amounts borrowed under the Credit Facility are secured by essentially all of the assets of the Company. The Credit Facility contains various representations and warranties, and restrictive covenants that, among other things and subject to specified exceptions, restrict the ability of us and our restricted subsidiaries to grant liens, incur indebtedness (including guarantees), make investments, engage in mergers and acquisitions, make dispositions of assets, make restricted payments or change the nature of our or their business. The Credit Facility contains financial covenants related to the consolidated net leverage ratio and the fixed charge coverage ratio (as defined in the Credit Facility). The restricted covenants after giving effect to Amendment No. 2 to Credit Agreement and Waiver (the “Amendment”) are described more fully below. The Credit Facility also contains certain affirmative covenants, including reporting requirements, such as delivery of financial statements, certificates and notices of certain events, maintaining insurance and providing additional guarantees and collateral in certain circumstances. The Credit Facility includes customary events of default, including non-payment of principal, interest or fees, violation of covenants, inaccuracy of representations or warranties, cross default to certain other material indebtedness, bankruptcy and insolvency events, invalidity or impairment of guarantees or security interests, material judgments and change of control. The Revolving Loan provides a principal amount of up to $50,000 , reduced by outstanding letters of credit. As of September 30, 2019 , $10,215 was outstanding on the Revolving Loan and $11,980 of letters of credit were outstanding. But for the Amendment, as of June 30, 2019, we would not have been in compliance with the requirement to maintain a consolidated net leverage ratio of 3.75 to 1.00 under the Credit Facility. On August 13, 2019, we entered into the Amendment, pursuant to which, among other things, the required lenders agreed to waive such non-compliance. In addition, pursuant to the terms of the Amendment, the Credit Facility was amended to revise the required financial covenant ratios such that, after giving effect to the Amendment, we are not required to comply with any financial covenants through March 30, 2020. After March 30, 2020, we will be required to comply with a consolidated net leverage ratio of 6.50 to 1.00 from March 31, 2020 through September 29, 2020, decreasing to 3.00 to 1.00 as of September 30, 2020 and thereafter. After giving effect to the Amendment, we will also be required to comply with a fixed charge coverage ratio of 0.75 to 1.00 as of March 31, 2020, 0.90 to 1.00 as of June 30, 2020 and 1.20 to 1.00 thereafter. In the event that we are unable to comply in the future with such financial covenants upon delivery of our financial statements pursuant to the terms of the Credit Facility, an Event of Default will have occurred and the Administrative Agent can then, following a specified cure period, declare the unpaid principal amount of all outstanding loans, all interest accrued and unpaid thereon, and all other amounts payable to be immediately due and payable by the Company. As consideration for the accommodations described above, we have agreed that amounts borrowed pursuant to the Delayed Draw Commitment will not exceed $15,000 at any one time outstanding (without reducing the overall Delayed Draw Commitment amount). In addition, any Delayed Draw Term Loans shall incur additional interest at a rate equal to 10.0% per annum on all amounts outstanding in excess of $10,000 of Delayed Draw Term Loans. Further, the margin of interest that will be charged on all outstanding loans has been increased to 4.00% for loans based on LIBOR and 3.00% for loans based on the alternative base rate. The Amendment revised the amount of (i) the commitment fees to 0.35% at all times for unused portions of the Credit Facility and (ii) fees on outstanding letters of credit to 3.35% at all times. The Amendment also added a requirement to make two additional scheduled prepayments of outstanding loans under the Credit Facility, including a payment of $50,000 on or before September 13, 2019 and an additional payment of $40,000 on or before March 31, 2020. The $50,000 payment was made prior to September 13, 2019, using the payment collected related to the early completion of the Brickhaven deemed termination. Regarding the March 2020 debt payment of $40,000 , management has evaluated its ability to make this payment and meet our other financial obligations using our most recent financial forecast, which includes consideration of projected cash flows from operations, anticipated availability under the Credit Facility and prudent working capital management. The financial forecast does not anticipate incurring material unexpected losses in existing operations or new work awards being materially delayed. Though management believes that the Company will not be able to make the $40,000 payment due in March 2020 and meet our other obligations as they become due over the next year based solely on projected cash flows from operations, anticipated availability under the revolving credit facility and prudent working capital management, we expect to execute transactions and/or utilize other sources of funding that provide additional liquidity necessary to meet our obligations as they become due. We are actively pursuing, with authority from the Board of Directors, a variety of strategic transactions and cost-cutting measures, including, but not limited to, asset divestitures, alternative sources of capital, reduction in corporate discretionary expenditures and capital expenditures, and other operational efficiencies. We believe it is probable that these measures, as we continue to implement them, will enable us to make this payment and meet our other obligations as they become due through at least 12 months from the date that these financial statements were issued. If these initiatives are not successful or other unanticipated headwinds in our business occur, the Company could be required to amend or obtain a waiver from the Administrative Agent, and there is no assurance that we could obtain such amendment or waiver. If we are unable to complete such initiatives by the required debt payment due dates and we are unable to obtain an amendment or waiver from the Administrative Agent, the Company has the ability to access additional related party funding. The Amendment also includes revisions to the restrictive covenants, including removing certain exceptions to the restrictions on our ability to make acquisitions, to make investments and to make dividends or other distributions. After giving effect to the Amendment, we will not be permitted to make any distributions or dividends to our stockholders without the consent of the required lenders.

On August 13, 2019, we entered into the Amendment, pursuant to which, among other things, the required lenders agreed to waive such non-compliance. In addition, pursuant to the terms of the Amendment, the Credit Facility was amended to revise the required financial covenant ratios such that, after giving effect to the Amendment, we are not required to comply with any financial covenants through March 30, 2020. After March 30, 2020, we will be required to comply with a consolidated net leverage ratio of 6.50 to 1.00 from March 31, 2020 through September 29, 2020, decreasing to 3.00 to 1.00 as of September 30, 2020 and thereafter. After giving effect to the Amendment, we will also be required to comply with a fixed charge coverage ratio of 0.75 to 1.00 as of March 31, 2020, 0.90 to 1.00 as of June 30, 2020 and 1.20 to 1.00 thereafter. In the event that we are unable to comply in the future with such financial covenants upon delivery of our financial statements pursuant to the terms of the Credit Facility, an Event of Default will have occurred and the Administrative Agent can then, following a specified cure period, declare the unpaid principal amount of all outstanding loans, all interest accrued and unpaid thereon, and all other amounts payable to be immediately due and payable by the Company. As consideration for the accommodations described above, we have agreed that amounts borrowed pursuant to the Delayed Draw Commitment will not exceed $15,000 at any one time outstanding (without reducing the overall Delayed Draw Commitment amount). In addition, any Delayed Draw Term Loans shall incur additional interest at a rate equal to 10.0% per annum on all amounts outstanding in excess of $10,000 of Delayed Draw Term Loans. Further, the margin of interest that will be charged on all outstanding loans has been increased to 4.00% for loans based on LIBOR and 3.00% for loans based on the alternative base rate. The Amendment revised the amount of (i) the commitment fees to 0.35% at all times for unused portions of the Credit Facility and (ii) fees on outstanding letters of credit to 3.35% at all times. The Amendment also added a requirement to make two additional scheduled prepayments of outstanding loans under the Credit Facility, including a payment of $50,000 on or before September 13, 2019 and an additional payment of $40,000 on or before March 31, 2020. The $50,000 payment was made prior to September 13, 2019, using the payment collected related to the early completion of the Brickhaven deemed termination. Regarding the March 2020 debt payment of $40,000 , management has evaluated its ability to make this payment and meet our other financial obligations using our most recent financial forecast, which includes consideration of projected cash flows from operations, anticipated availability under the Credit Facility and prudent working capital management. The financial forecast does not anticipate incurring material unexpected losses in existing operations or new work awards being materially delayed. Though management believes that the Company will not be able to make the $40,000 payment due in March 2020 and meet our other obligations as they become due over the next year based solely on projected cash flows from operations, anticipated availability under the revolving credit facility and prudent working capital management, we expect to execute transactions and/or utilize other sources of funding that provide additional liquidity necessary to meet our obligations as they become due. We are actively pursuing, with authority from the Board of Directors, a variety of strategic transactions and cost-cutting measures, including, but not limited to, asset divestitures, alternative sources of capital, reduction in corporate discretionary expenditures and capital expenditures, and other operational efficiencies. We believe it is probable that these measures, as we continue to implement them, will enable us to make this payment and meet our other obligations as they become due through at least 12 months from the date that these financial statements were issued. If these initiatives are not successful or other unanticipated headwinds in our business occur, the Company could be required to amend or obtain a waiver from the Administrative Agent, and there is no assurance that we could obtain such amendment or waiver. If we are unable to complete such initiatives by the required debt payment due dates and we are unable to obtain an amendment or waiver from the Administrative Agent, the Company has the ability to access additional related party funding. The Amendment also includes revisions to the restrictive covenants, including removing certain exceptions to the restrictions on our ability to make acquisitions, to make investments and to make dividends or other distributions. After giving effect to the Amendment, we will not be permitted to make any distributions or dividends to our stockholders without the consent of the required lenders.

Share-based Payment Arrangement [Abstract]
Stock/Unit Based Compensation	Stock/Unit-Based Compensation The Limited Liability Company Agreement for Charah Management provided for the issuance of up to 1,000 Series C profits interests (the “Charah Series C Profits Interests”). In 2017, Charah Management adopted the Charah Series C Profits Interest Plan and issued 650 of such units to employees. The Charah Series C Profits Interests participated in distributions to Charah members based on specified rates of return being realized on the Charah Management LLC Series A Membership Interests and the Charah Management LLC Series B Membership Interests. The Charah Series C Profits Interest Plan is no longer in place following our corporate reorganization and related IPO. The Charah Series C Profits Interests would have vested ratably in each of the first five anniversaries of their grant date with vesting accelerated upon a change of control. There were 540 Charah Series C Profits Interests unvested at June 18, 2018, which were canceled as a result of the corporate reorganization that occurred upon the closing of the IPO (see further discussion below). The Limited Liability Company Agreement for Allied provided for the issuance of up to 1,000 Series C profits interests (the “Allied Series C Profits Interests”). In 2017, Allied adopted the Allied Series C Profits Interest Plan and issued 550 of such units to employees. The Allied Series C Profits Interests participated in distributions to Allied members based on specified rates of return being realized on the Allied Power Management, LLC Series A Membership Interests and the Allied Power Management, LLC Series B Membership Interests. The Allied Series C Profits Interest Plan is no longer in place following our corporate reorganization and related IPO. The Allied Series C Profits Interests vested immediately upon grant. In connection with the corporate reorganization that occurred upon the closing of the IPO, the holders of the Charah Series C Profits Interests and the Allied Series C Profits Interests received 1,215,956 shares of common stock (the “Management Reorganization Consideration”) in exchange for the contribution to the Company of their Charah Series C Profits Interests and Allied Series C Profits Interests. Of these shares, 303,993 vested immediately and 911,963 are subject to time-based vesting conditions, as well as performance vesting conditions, based on specified EBITDA targets and achievement of certain safety metrics, which will be determined at a future date. In addition, 272,708 shares of common stock were issued under the Charah Solutions, Inc. 2018 Omnibus Incentive Plan (the “2018 Plan”). Of these shares, 68,176 vested immediately and 204,532 are subject to the same time-based vesting conditions and performance vesting conditions as the shares issued as part of the Management Reorganization Consideration. The fair value of the awards was calculated initially as $12 per share, and will be updated thereafter for changes at each reporting period until the performance targets are approved by the Company’s board of directors. The fair value of the awards is recognized over the required service period for each grant. As of September 30, 2019 , 500,253 of the shares subject to time-based and performance vesting conditions were vested. Upon the closing of the IPO, the board of directors of the Company adopted the 2018 Plan, pursuant to which employees, consultants and directors of the Company and its affiliates, including named executive officers, are eligible to receive awards. The 2018 Plan provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, bonus stock, dividend equivalents, other stock-based awards, substitute awards, annual incentive awards and performance awards intended to align the interests of participants with those of Company stockholders. The Company has reserved 3,006,582 shares of common stock for issuance under the 2018 Plan, and all future equity awards described above will be issued pursuant to the 2018 Plan. During the three months ended June 30, 2018, the Company issued 44,198 shares under the 2018 Plan that vested after one year . The fair value of the awards was calculated as $12 per share, which was recognized over the one year vesting period. As of September 30, 2019 , 31,577 of the shares were vested and 12,621 had been forfeited. During the three months ended September 30, 2018, the Company issued 45,004 shares under the 2018 Plan that vested after one year . The fair value of the awards was calculated as $7.67 per share, which was recognized over the one year vesting period. As of September 30, 2019 , 36,670 of the shares were vested and 8,334 had been forfeited. There were no grants or awards during the three months ended September 30, 2019 . During the nine months ended September 30, 2019 , the Company granted 755,455 restricted stock units (“RSUs”) under the 2018 Plan that are time-based. Of these RSUs, 116,381 vest after one year , 550,106 vest in equal installments over three years , and 88,968 vest in equal installments over four years . The fair value of these RSUs is based on the market price of the Company's shares on the grant date. As of September 30, 2019 , none of the shares were vested. During the nine months ended September 30, 2019 , we also granted 330,628 performance share units (“PSUs”) under the 2018 Plan that cliff vest after three years . The vesting of these PSUs is dependent upon the Company’s achievement of certain stock price metrics. The fair value of the PSUs was determined using a binomial lattice model based upon the grant date stock price, a risk-free interest rate of 2.29% based upon the U.S. Treasury yield curve in effect at the time of the grants, and an assumed volatility rate of 30% based upon a comparable public company analysis. As of September 30, 2019 , none of the shares were vested. A summary of the Company’s non-vested share activity for the nine months ended September 30, 2019 is as follows: Shares Weighted-Average Fair Value Weighted-Average Remaining Contractual Terms (Years) Aggregate Intrinsic Value Outstanding as of December 31, 2018 1,198,703 $ 11.84 0.77 $ 10,009 Granted 1,086,083 5.95 Forfeited (308,477 ) 9.84 Vested (568,500 ) 10.49 Outstanding as of September 30, 2019 1,407,809 $ 6.76 1.51 $ 2,985 Stock-based compensation expense related to the shares issued as part of the Management Reorganization Consideration and the 2018 Plan was $659 and $1,046 during the three months ended September 30, 2019 and 2018 , respectively, and $1,666 and $2,235 during the nine months ended September 30, 2019 and 2018 , respectively. As of September 30, 2019 , total unrecognized stock-based compensation expense related to non-vested awards, net of estimated forfeitures, was $4,436 , and is expected to be recognized over a weighted-average period of 1.84 years. The total fair value of awards vested for the three and nine months ended September 30, 2019 was $281 and $5,966 , respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies We are party to a lawsuit filed against North Carolina by an environmental advocacy group alleging that the issuance by the state of certain permits associated with our Brickhaven clay mine reclamation site exceeded the state’s power. Although the state’s authority to issue the bulk of the permits (i.e., the allowance to reclaim the original site with coal ash) was upheld, the portion of the permits that allows us to “cut and prepare” an additional portion of the site was held by the North Carolina Superior Court to exceed the relevant agency’s statutory authority. The North Carolina Superior Court’s decision was reversed and remanded back to the North Carolina Office of Administrative Hearing. Dispositive motions filed by us and the North Carolina Department of Environmental Quality are pending before the North Carolina Office of Administrative Hearing. All customer related work at the Brickhaven site has been completed. Allied and its affiliate, Allied Power Resources, LLC, have been named in a collective action lawsuit filed in the U.S. District Court for the Northern District of Illinois, alleging violations of the Fair Labor Standards Act, and which includes related class claims alleging violations of the Illinois Minimum Wage Law and the Pennsylvania Minimum Wage Act for failure to pay overtime. This case is one of a series filed against companies in the oil, gas and energy industries in Illinois and Texas. The parties mediated this case in November 2018 and reached a settlement, contingent upon court approval. The parties are working to finalize the joint motion to approve the settlement to submit to the court for approval. In addition to the above matters, we are from time to time party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of our business. With respect to all such lawsuits, claims and proceedings, we record reserves when it is probable a liability has been incurred and the amount of loss can be reasonably estimated. Although it is difficult to predict the ultimate outcome of these lawsuits, claims and proceedings, we do not believe that the ultimate disposition of any of these matters, individually or in the aggregate, would have a material adverse effect on our results of operations, financial position or cash flows. We maintain liability insurance for certain risks that is subject to certain self-insurance limits. We believe amounts previously recorded are sufficient to cover any liabilities arising from the proceedings with all outstanding legal claims. Except as reflected in such accruals, we are currently unable to estimate a range of reasonably possible loss, or a range of reasonably possible loss in excess of the amount accrued, for outstanding legal matters.

Segment Reporting [Abstract]
Business Segment and Related Information	Business Segment and Related Information The Company has identified two reportable segments, Environmental Solutions and Maintenance and Technical Services, as each met the quantitative threshold of generating revenue equal to or greater than 10% of the combined revenue of all operating segments. The accounting policies applied to determine the segment information are the same as those described under “Critical Accounting Policies and Estimates” in Part II, “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2018. Management evaluates the performance of each segment based on segment gross profit, which is calculated as revenue less cost of sales. For the nine months ended September 30, 2019 and 2018 , there were no intersegment revenue or other intersegment transactions. Segment assets are also evaluated by management based on each segment’s investment in property and equipment. Assets (other than property and equipment and goodwill) are not allocated to segments. Summarized financial information with respect to the reportable segments is as follows: Three Months Ended September 30, 2019 Environmental Solutions Maintenance and Technical Services All Other Total Segment revenue $ 46,013 $ 75,100 $ — $ 121,113 Segment gross profit 6,789 7,070 — 13,859 Segment depreciation and amortization expense 1,394 2,014 1,991 5,399 Three Months Ended September 30, 2018 Environmental Solutions Maintenance and Technical Services All Other Total Segment revenue $ 103,848 $ 82,154 $ — $ 186,002 Segment gross profit 19,852 6,854 — 26,706 Segment depreciation and amortization expense 13,050 1,720 1,993 16,763 Nine Months Ended September 30, 2019 Environmental Solutions Maintenance and Technical Services All Other Total Segment revenue $ 141,346 $ 263,961 $ — $ 405,307 Segment gross profit 5,868 21,305 — 27,173 Segment depreciation and amortization expense 5,084 5,980 5,970 17,034 Expenditures for segment assets 8,890 4,750 32 13,672 Nine Months Ended September 30, 2018 Environmental Solutions Maintenance and Technical Services All Other Total Segment revenue $ 241,745 $ 295,509 $ — $ 537,254 Segment gross profit 54,417 21,936 — 76,353 Segment depreciation and amortization expense 23,794 4,127 5,977 33,898 Expenditures for segment assets 7,165 7,761 22 14,948 As of September 30, 2019 Environmental Solutions Maintenance and Technical Services All Other Total Segment property and equipment, net $ 48,990 $ 36,339 $ 245 $ 85,574 Segment goodwill 57,591 16,622 — 74,213 As of December 31, 2018 Environmental Solutions Maintenance and Technical Services All Other Total Segment property and equipment, net $ 47,467 $ 41,155 $ 319 $ 88,941 Segment goodwill 57,591 16,622 — 74,213 The following is a reconciliation of segment gross profit to net loss: Three Months Ended Nine Months Ended September 30, September 30, 2019 2018 2019 2018 Segment gross profit $ 13,859 $ 26,706 $ 27,173 $ 76,353 General and administrative expenses (14,096 ) (32,625 ) (45,481 ) (65,944 ) Interest expense, net (3,833 ) (17,034 ) (12,987 ) (26,708 ) Income from equity method investment 667 786 1,884 2,072 Income tax benefit 1,100 5,667 7,489 2,761 Net loss $ (2,303 ) $ (16,500 ) $ (21,922 ) $ (11,466 ) The following is a reconciliation of segment assets to total assets: As of September 30, 2019 As of December 31, 2018 Segment property and equipment, net $ 85,574 $ 88,941 Segment goodwill 74,213 74,213 Non-segment assets 222,045 295,747 Total assets $ 381,832 $ 458,901 Summarized financial information with respect to the types of revenue recognized is as follows: Three Months Ended September 30, 2019 Products Percentage of Completion Services Total Revenue $ 28,995 $ 16,841 $ 75,277 $ 121,113 Three Months Ended September 30, 2018 Products Percentage of Completion Services Total Revenue $ 26,243 $ 75,819 $ 83,940 $ 186,002 Nine Months Ended September 30, 2019 Products Percentage of Completion Services Total Revenue $ 76,397 $ 63,048 $ 265,862 $ 405,307 Nine Months Ended September 30, 2018 Products Percentage of Completion Services Total Revenue $ 57,809 $ 178,471 $ 300,974 $ 537,254

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s income tax benefit was $1,100 and $7,489 for the three and nine months ended September 30, 2019 , respectively, and $5,667 and $2,761 for the three and nine months ended September 30, 2018 , respectively. The Company’s effective income tax rate for the three and nine months ended September 30, 2019 was 32.3% and 25.5% , respectively. The effective income tax rate includes the effect of state income taxes, nondeductible items and benefits for noncontrolling interests. The Company evaluates its effective income tax rate at each interim period and adjusts it accordingly as facts and circumstances warrant. The determination of the annual estimated effective income tax rate at each interim period requires certain estimates and judgments including, but not limited to, the expected operating income for the year, estimated permanent differences between book and tax amounts, and the likelihood of recovering deferred tax assets generated in the current year, primarily net operating loss and other carryforwards, and our ability to uphold certain tax positions. The accounting estimates used to compute the provision for income taxes may change as new events occur and additional information is obtained. At September 30, 2019 , deferred tax assets, net of deferred tax liabilities, was $10,250 . A valuation allowance is recorded if it is more likely than not that a portion of the Company’s deferred tax assets will not be realized. The Company evaluates both the positive and negative evidence in determining the need for a valuation allowance on its deferred tax assets. Realization of net operating losses and other carryforwards is dependent upon generating sufficient taxable income in the appropriate jurisdiction prior to the expiration of the carryforward periods, which involves business plans, planning opportunities and expectations about future outcomes. Although realization is not assured, management believes it is more likely than not that our deferred tax assets will be realized. Therefore, no valuation allowance has been recorded for our deferred tax assets. The Company will continue to evaluate the need for a valuation allowance on its deferred tax assets in future periods.

Loss Per Share

Earnings Per Share [Abstract]
Loss Per Share	Loss Per Share Basic loss per share is computed by dividing net loss attributable to the Company’s stockholders by the weighted-average number of shares outstanding during the period. Diluted loss per share reflects all potential dilutive ordinary shares outstanding during the period and is computed by dividing net loss attributable to the Company’s stockholders by the weighted-average number of shares outstanding during the period increased by the number of additional shares that would have been outstanding as dilutive securities. For the periods prior to the IPO, the average number of ordinary shares outstanding used to calculate basic and diluted loss per share was based on the ordinary shares that were outstanding at the time of the IPO. As a result of the net loss per share for the three and nine months ended September 30, 2019 , the inclusion of all potentially dilutive shares would be anti-dilutive. Therefore, dilutive shares (in thousands) of 1,510 and 1,299 were excluded from the computation of the weighted-average shares for diluted net loss per share for the three and nine months ended September 30, 2019 , respectively. Basic and diluted loss per share is determined using the following information: Three Months Ended Nine Months Ended September 30, September 30, 2019 2018 2019 2018 Numerator: Net loss attributable to Charah Solutions, Inc. $ (3,313 ) $ (17,395 ) $ (24,158 ) $ (13,370 ) Denominator (in thousands): Weighted-average shares outstanding 29,605 29,083 29,452 25,777 Dilutive share-based awards — — — — Total weighted-average shares outstanding, including dilutive shares 29,605 29,083 29,452 25,777 Basic loss per share $ (0.11 ) $ (0.60 ) $ (0.82 ) $ (0.52 ) Diluted loss per share $ (0.11 ) $ (0.60 ) $ (0.82 ) $ (0.52 )

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis for Presentation The Company’s fiscal year ends December 31. The accompanying unaudited condensed consolidated and combined financial statements include the assets, liabilities, stockholders’ and members’ equity, and results of operations of the Company and its consolidated and combined subsidiaries. Intercompany transactions and balances have been eliminated in consolidation. The accompanying unaudited condensed consolidated and combined financial statements have been prepared in accordance with rules and regulations of the Securities and Exchange Commission for quarterly reports on Form 10-Q. In the opinion of management, all adjustments considered necessary for a fair presentation have been included, which consist of normal recurring adjustments. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted. The accompanying unaudited condensed consolidated and combined financial statements should be read in conjunction with the audited consolidated and combined financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2018.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) , requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The core principle of Accounting Standards Codification (“ASC”) Topic 606 is to recognize revenue when a customer obtains control of a good or service, in an amount that reflects the consideration to which an entity is expected to be entitled for those goods or services. Additionally, this ASU requires enhanced qualitative and quantitative disclosures regarding customer contracts. This ASU will replace most existing revenue recognition guidance in GAAP when it becomes effective and permits the use of either a full retrospective transition method or a modified retrospective with cumulative effect transition method. To assess the impact of this ASU, we utilized internal resources to lead the implementation effort and supplemented them with external resources. The Company’s adoption activities were performed over three phases: (i) assessment, (ii) design and (iii) implementation using a cross-functional team that included accounting, operational and information technology personnel. Based on our work to date, we believe we have identified all material contract types, revenue and costs that may be impacted by implementing ASC Topic 606. Generally, the Company believes the majority of its contracts will have similar performance obligations under ASC Topic 606 as compared with the units of account previously identified. We have identified certain contracts where the timing of revenue recognition will change under ASC Topic 606. Prior to the adoption of ASC Topic 606, revenue recorded for certain contracts with fluctuating rates per unit matched the amount that was billed to the customer. In accordance with ASC Topic 606, for contracts with fluctuating rates per unit that are not directly related to changes in the Company’s effort to perform under the contract, the Company will recognize revenue based on the stand-alone selling price per unit, calculated as the average rate per unit over the term of those contractual rates. This accounting treatment will at times create a contract asset or liability for the difference between the revenue recognized and the amount billable/billed to the customer. As a calendar year-end emerging growth company that has elected to take advantage of the extended transition period for complying with new or revised financial accounting standards, we are required to adopt the new revenue standard for annual periods beginning on January 1, 2019, and for interim periods within annual periods beginning on January 1, 2020. Accordingly, the interim periods within the year ending December 31, 2019 will be reported under the existing revenue standard, ASC Topic 605, while the annual period for the year ending December 31, 2019 will be reported under ASC Topic 606. For the annual period for the year ending December 31, 2019, we will apply the requirements of ASC Topic 606 to all contracts using the modified retrospective with cumulative effect transition method. Accordingly, we will recognize the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of retained earnings for the year ending December 31, 2019. The comparative information will not be restated and will continue to be reported under the accounting standards in effect for the comparative periods. Based upon our assessment of the impact of the adoption of ASC Topic 606, we estimate a decrease of approximately $300 to the opening balance of retained earnings as of January 1, 2019, with an associated decrease in the contract asset balance “costs and estimated earnings in excess of billings.” In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , requiring all leases to be recognized on the balance sheet as a right-of-use asset and a lease liability, unless the lease is a short-term lease (generally a lease with a term of 12 months or less). At the commencement date of the lease, the Company will recognize: (i) a lease liability for the Company’s obligation to make payments under the lease agreement, measured on a discounted basis; and (ii) a right-of-use asset that represents the Company’s right to use, or control the use of, the specified asset for the lease term. This ASU originally required recognition and measurement of leases at the beginning of the earliest period presented using a modified retrospective transition method. In July 2018, the FASB issued ASU No. 2018-11, which provided an additional (and optional) transition method that permits application of this ASU at the adoption date with recognition of a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. In October 2019, the FASB delayed the effective date of this ASU, extending the effective date for non-public business entities and making the ASU effective for the Company for the fiscal year ending December 31, 2021, and interim periods within the fiscal year ending December 31, 2022, with early adoption permitted. The Company has not yet selected a transition method and is currently evaluating the effect that the adoption of this ASU will have on its consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments — Credit Losses (Topic 326) — Measurement of Credit Losses on Financial Instruments , which introduces a new model for recognizing credit losses on financial instruments based on an estimate of current expected credit losses. The new model will apply to: (1) loans, accounts receivable, trade receivables, and other financial assets measured at amortized cost, (2) loan commitments and certain other off-balance sheet credit exposures, (3) debt securities and other financial assets measured at fair value through other comprehensive income, and (4) beneficial interests in securitized financial assets. The amendments contained in this ASU will be applied through a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. In November 2018, the FASB issued ASU No. 2018-19, which amended the effective date of ASU No. 2016-13 and clarified that receivables arising from operating leases are not within the scope of Subtopic 326-20. In October 2019, the FASB delayed the effective date of this ASU, extending the effective date for non-public business entities and making the ASU effective for the Company for the fiscal year ending December 31, 2023, and interim periods therein, with early adoption permitted. The Company is currently evaluating the effect that the adoption of this ASU will have on its consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments . This ASU addresses specific cash flow issues, including debt prepayment or debt extinguishment costs, contingent consideration payments made after a business combination, and proceeds from the settlement of insurance claims. This ASU is effective for the Company for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. The Company is currently evaluating the effect that the adoption of this ASU will have on its consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230) . This ASU requires that a statement of cash flows explains the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Upon adopting this ASU, amounts generally described as restricted cash or restricted cash equivalents will be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the consolidated statement of cash flows. ASU No. 2016-18 is effective for the Company for interim and annual periods beginning after December 15, 2018. The Company adopted ASU No. 2016-18 effective January 1, 2019, with retrospective application to our consolidated and combined statements of cash flows so that the consolidated and combined statements of cash flows present a reconciliation of the changes in cash and cash equivalents and restricted cash. The adoption of this ASU did not have a material impact on our consolidated financial statements. As a result of this retrospective adoption, the amount of cash and cash equivalents previously presented in the consolidated and combined statements of cash flows increased by $3,358 to reflect the inclusion of restricted cash in the amount reported for changes in cash, cash equivalents and restricted cash as of the beginning and end of the period for the period from January 1, 2017 through January 12, 2017 and as of the beginning of the period for the period from January 13, 2017 through December 31, 2017. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . This ASU simplifies the measurement of goodwill impairment by eliminating the requirement that an entity compute the implied fair value of goodwill based on the fair values of its assets and liabilities to measure impairment. Instead, goodwill impairment will be measured as the difference between the fair value of the reporting unit and the carrying value of the reporting unit. This ASU also clarifies the treatment of the income tax effect of tax-deductible goodwill when measuring goodwill impairment loss. In October 2019, the FASB delayed the effective date for implementation of ASU No.2017-04. The Company will be required to adopt ASU No. 2017-04 for annual and any interim impairment tests for the periods beginning after January 1, 2023. ASU No. 2017-04 must be applied prospectively, with early adoption permitted. The Company is currently evaluating the effect that the adoption of this ASU will have on its consolidated financial statements.
