Basis of Presentation	9 Months Ended
Basis of Presentation	Sep. 30, 2018
Basis of Presentation [Abstract]
Basis of Presentation	Note 1. Basis of Presentation Nature of Business NCS Multistage Holdings, Inc., through its wholly owned subsidiaries and subsidiaries for which we have a controlling voting interest (collectively referred to as the “Company,” “NCS,” “we” or “us”), is primarily engaged in providing engineered products and support services for oil and natural gas well completions and field development strategies. We offer our products and services primarily to exploration and production companies for use in onshore wells. We operate through service facilities principally located in Houston, Midland and Corpus Christi, Texas; Tulsa and Oklahoma City, Oklahoma; and Calgary, Red Deer, Grande Prairie and Estevan, Canada. Basis of Presentation Our accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), issued by the Securities Exchange Commission (“SEC”) and have not been audited by our independent registered public accounting firm. The Condensed Consolidated Balance Sheet at December 31, 2017 is derived from our audited financial statements. However, certain information and footnote disclosures required by GAAP for complete annual financial statements have been omitted or condensed as permitted by the rules and regulations of the SEC, and, therefore, these interim financial statements should be read in conjunction with our audited financial statements included in our Annual Report on Form 10-K filed with the SEC on March 9, 2018. In the opinion of management, these condensed consolidated financial statements, which have been prepared pursuant to the rules of the SEC and GAAP for interim financial reporting, reflect all adjustments, which consisted only of normal recurring adjustments that were necessary for a fair statement of the interim periods presented. The results of operations for interim periods are not necessarily indicative of those for a full year. All intercompany accounts and transactions have been eliminated for purposes of preparing these condensed consolidated financial statements. Summary of New Significant Accounting Policy Intangible Assets Certain costs incurred in the development of internal-use software applications are capitalized and costs incurred outside of the software application development stage are expensed as incurred. The amounts capitalized are included in intangibles, categorized as internally developed software, and will be amortized on a straight-line basis over the estimated useful life of the software, which is five years. We will begin to amortize internal-use software when it is ready for its intended use. Recent Accounting Pronouncements Pronouncements Adopted in 2018 In June 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-07, Improvements to Nonemployee Share-Based Payment Accounting (Topic 718). The ASU is intended to reduce the cost and complexity and to improve financial reporting for nonemployee share-based payments. The ASU expands the scope of Topic 718 to include share-based payments issued to nonemployees for goods or services. Consequently, the accounting for share-based payments to nonemployees and employees will be substantially aligned. The ASU is for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606, Revenue from Contracts with Customers. We elected to early adopt this ASU effective April 1, 2018. The adoption of this ASU did not have a material impact on our condensed consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business (Topic 805), to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. For public entities, this guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those periods. We adopted ASU 2017-01 effective January 1, 2018, which did not have a material impact on our condensed consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments (Topic 230). The objective of the guidance is to reduce the existing diversity in practice related to the presentation and classification of certain cash receipts and cash payments. The guidance addresses eight specific cash flow issues including but not limited to, debt prepayment or extinguishment costs, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims and proceeds from the settlement of corporate-owned life insurance policies. For public entities, the guidance is effective for financial statements issued for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years and is retrospective for all periods presented. Early adoption is permitted including for interim periods. We adopted ASU 2016-15 effective January 1, 2018, which did not have a material impact on our condensed consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). The new standard is effective for annual reporting periods beginning after December 15, 2017 and early adoption is permitted, however, not before fiscal years beginning after December 15, 2016. Subsequent to ASU 2014-09’s issuance, Topic 606 was amended for FASB updates that changed the effective date as well as addressed certain aspects regarding new revenue standards. The comprehensive new standard supersedes existing revenue recognition guidance and requires revenue to be recognized when promised goods or services are transferred to customers in amounts that reflect the consideration to which entities expect to be entitled in exchange for those goods or services. Adoption of the new rules could affect the timing of revenue recognition for certain transactions. The guidance permits the use of either a full retrospective or modified retrospective transition method. On January 1, 2018, we adopted ASU 2014-09 and its related amendments (collectively known as Accounting Standards Codification “ASC 606”), using the modified retrospective method. We have concluded that the adoption of this ASU did not have a material impact on our condensed consolidated financial statements. See “Note 2. Revenue” for the required disclosures related to the impact of adopting this standard. Pronouncements Not Yet Effective In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40). The ASU aligns the requirements to capitalize implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements to capitalize implementation costs incurred to develop or obtain internal-use software. For public entities, this guidance is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. We are currently evaluating the impact of the adoption of this guidance. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820). The ASU modifies, removes and adds certain disclosure requirements on fair value measurements. For public entities, this guidance is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted for all amendments. Further, entities may early adopt eliminated or modified disclosure requirements and delay the adoption of all new disclosure requirements until the effective date. We are currently evaluating the impact of the adoption of this guidance. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which replaces the existing guidance in ASC 840, Leases. Under ASC 842, lessees will need to recognize most leases on their balance sheets as lease liabilities with corresponding right-of-use assets. The new lease standard also changes the definition of a lease and requires expanded quantitative and qualitative disclosures for both lessees and lessors. Topic 842 was subsequently amended to address certain aspects regarding the new lease standard in addition to offering a new transition method, whereby comparative periods presented in the financial statements in the period of adoption do not need to be restated. Entities are required to adopt ASC 842 using a modified retrospective transition method. Certain practical expedients can be applied. The new standard is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. We plan to adopt ASC 842 effective January 1, 2019 and are currently assessing the impact of the adoption. During the second quarter of 2018, we put in place a team, including a third-party consultant, to execute the transition efforts related to the new guidance. We compiled an initial inventory of lease contracts and initiated lease contract reviews. We continue to take steps to update the lease contract inventory and will proceed through our plan for calculations needed for the balance sheet and income statement as well as evaluate additional changes to our business processes and internal controls. While we cannot currently estimate the quantitative effect that ASC 842 will have on our condensed consolidated financial statements, the adoption of ASC 842 will increase our asset and liability balances on the condensed consolidated balance sheets due to the required recognition of right-of-use assets and corresponding lease liabilities for most lease obligations that are currently classified as operating leases. We also plan to utilize the FASB package of three practical expedients under ASC 842-10-65-1(f).

Note 2. Revenues

On January 1, 2018, we adopted ASC 606 and elected to use the modified retrospective method for all contracts not completed as of the date of adoption. The reported results for 2018 reflect the application of ASC 606 guidance while the reported results for 2017 were prepared under the guidance of ASC 605, Revenue Recognition. In accordance with ASC 606, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services if certain criteria are met.

Financial Statement Impact of Adopting ASC 606

The cumulative effect of the changes made to our condensed consolidated balance sheet at January 1, 2018 for the adoption of ASC 606 using the modified retrospective method was as follows (in thousands):

Revenue Recognition

We derive our revenues primarily from highly engineered products and support services. Revenues are based upon a purchase order, contract or other persuasive evidence of an arrangement with the customer that includes a fixed or determinable price, provided that collectability is reasonably assured, but such arrangements do not generally include right of return or other similar provisions or other significant post-delivery obligations. Sales and value added taxes that we collect concurrent with revenue-producing activities are excluded from revenue. We determine revenue recognition through the following steps: (i) identify the contract, (ii) identify the performance obligations, (iii) determine the transaction price, (iv) allocate the transaction price and (v) satisfy the performance obligation.

On occasion, we issue credits to our customers that are related specifically to the performance of our products or the services we provide, with such credits reducing the amount of revenue for that sale or job. Such credits are infrequent, situation-specific and cannot be estimated in advance.

The payment terms and conditions in our customer contracts vary. We do not have contracts that contain a financing component and do not accept noncash consideration from customers.

NCS has elected to recognize shipping and handling costs when the control of the product transfers to the customer. These costs are included in cost of sales in our condensed consolidated statements of income.

Product Sales Revenues

For product sale arrangements that are standard inventory products or modified inventory products with an alternative use, revenue is recognized at a point in time when control transfers. Control generally transfers upon shipment or delivery, and delivery is based on the customer instructions. Customers may also request bill and hold arrangements in writing. Once we have completed the bill and hold order, the products are segregated from the rest of inventory in the warehouse. The transaction price for product sales having a performance obligation is the price per unit times the unit quantity ordered and shipped to the customer or consumed at the well site.

Services Revenue

For service arrangements that do not have a contract provision with a right to a payment for services up to the date of termination, revenue is recognized when the job has been completed, which usually includes a customer signature or acknowledgement and when there are no additional services or future obligations required by us. The transaction price is determined by the contract unit day rate times the cumulative number of days of service provided upon the completion of the service and upon customer acceptance.

For service arrangements that do have a contract provision with a right to payment for services up to the date of termination, revenue is recognized over time using a unit rate (labor and materials) output method that corresponds to the value we would receive upon termination of the contract at a reporting period. In applying the output method at the end of a quarter, we check that there is no material work in progress that is not in the measurement of the output. The transaction price for the period end is determined by the contract unit rate times the cumulative number of units earned up to the reporting period less any revenue recognized in prior periods.

Disaggregation of Revenue

We sell our products and services primarily in North America and in selected international markets. Revenue by geography is attributed based on the current billing address of the customer. The following table depicts the disaggregation of revenue by geographic region (in thousands):

Contract Balances

When the timing of the delivery of products and provision of services is different from the timing of the customer payments, we recognize either a contract asset (performance precedes contractual due date in connection with estimates of variable consideration) or a contract liability (customer payment precedes performance) on our condensed consolidated balance sheet. The following table includes the contract assets and liabilities as of September 30, 2018 and January 1, 2018 (in thousands):


	Contract Assets				Contract Liabilities
	Current		Non-Current		Current		Non-Current
Balance at January 1, 2018	$	—	$	—	$	170	$	—
Additions		—		—		372		—
Revenue recognized		—		—		(221)		—
Balance at September 30, 2018	$	—	$	—	$	321	$	—

Our contract liability as of September 30, 2018 is included in current liabilities on our condensed consolidated balance sheet. Our performance obligations for our product and service revenues are usually satisfied before the customer’s payment although prepayments may occasionally be required for international sales.

Contracts with Multiple Performance Obligations

Greater than 99% of our product and service revenues are considered a single performance obligation. Our self-service product line, which is less than one percent of our revenue for the three and nine months ended September 30, 2018, is made up of two performance obligations: (i) the delivery of tracer materials to a customer well site and (ii) the creation of diagnostic reports ordered by customers when we do not perform an integrated service. For these contracts, we do not allocate the transaction price as the individual performance obligations are sold at standalone prices in the customer order. The transaction prices for our self-service product line that have two performance obligations are (i) the price per unit times the quantity of tracer materials and (ii) prices charged for diagnostic reports ordered by and delivered to the customer.

Practical Expedients and Exemptions

We generally expense sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within selling, general and administrative expenses.

We do not disclose the value of unsatisfied performance obligations when the related contract has a duration of one year or less or we recognize revenue equal to what we have the right to invoice when that amount corresponds directly with the value to the customer of our performance to date.

Note 3. Acquisitions

Spectrum Tracer Services

On August 31, 2017, we acquired 100% of the equity interests in Spectrum Tracer Services, LLC (“Spectrum”) in exchange for approximately $83 million, subject to certain adjustments, which was comprised of (i) approximately $76 million in cash and (ii) 0.4 million shares of our common stock using a fair market value of $19.42 per share. The cash portion was funded with available cash and borrowings under our Senior Secured Credit Facility (as defined below). We believe Spectrum’s tracer diagnostics services offering strengthens our ability to provide our customers with actionable data and analysis to optimize oil and natural gas well completions and field development strategies.

The acquisition of Spectrum includes an earn-out provision that could provide up to $12.5 million in additional cash consideration to Spectrum’s former unitholders if Spectrum’s actual gross profit during the earn-out period that commenced on October 1, 2017 and ends on December 31, 2018 is greater than the earn-out threshold. The fair value of the earn-out recognized on the acquisition date was $0.4 million. We estimated the fair value of the earn-out using a risk-neutral option pricing analysis within a Monte Carlo simulation framework. The earn-out is subject to re-measurement each reporting period using Level 3 inputs until it has been paid. Subsequent changes in the fair value of the liability are reflected in our condensed consolidated statements of income as a change in fair value of contingent consideration. As of September 30, 2018, the earn-out had no value. As of December 31, 2017, the earn-out had a value of $3.4 million and was included in noncurrent contingent consideration on the condensed consolidated balance sheet. We recognized a benefit of $(2.0) million and $(9) thousand during the three months ended September 30, 2018 and 2017, respectively, and $(3.4) million and $(9) thousand for the nine months ended September 30, 2018 and 2017, respectively, as a change in fair value of contingent consideration expense in the condensed consolidated statements of income related to the fair value adjustment of the Spectrum earn-out. The cash payment, if any, is expected to be paid during the second quarter of 2019.

The following unaudited pro forma summary presents our select financial information as if the acquisition had occurred on January 1, 2016. The below information reflects pro forma adjustments based on available information and certain assumptions we believe are reasonable, including: (i) adjustments related to the depreciation and amortization of the fair value of acquired intangibles and fixed assets, (ii) removal of the historical interest expense of Spectrum as well as the addition of the interest expense of the borrowings under our Senior Secured Credit Facility in connection with the acquisition, (iii) tax effect related to historical U.S. operations and the aforementioned pro forma adjustments, (iv) adjustments related to the number of shares of our common stock outstanding to reflect the 0.4 million shares issued in connection with the acquisition and (v) accounting policy conformity changes. The pro forma condensed combined financial information has been included for comparative purposes and is not necessarily indicative of the results that might have actually occurred had the Spectrum acquisition taken place on January 1, 2016; furthermore, the financial information is not intended to be a projection of future results. The following table summarizes our unaudited selected financial information on a pro forma basis (in thousands, except per share data):


	Pro Forma (Unaudited)
	Three Months Ended		Nine Months Ended
	September 30, 2017		September 30, 2017
Revenue	$	61,516	$	170,294
Net income attributable to NCS Multistage Holdings, Inc.	$	1,971	$	5,625

The purchase price is allocated to the estimated fair value of assets acquired and liabilities assumed as of the acquisition date. Goodwill is calculated as the excess of the consideration transferred over the fair value of the net assets recognized. By combining Spectrum’s tracer diagnostics services offering with our existing portfolio of completions products and services, we believe we have an opportunity to increase our revenue through the cross-selling of tracer diagnostics services to current NCS customers and to sell NCS’s completions products and services to current Spectrum customers. This expected synergy gives rise to goodwill being recorded as part of the purchase price of Spectrum. The purchase price allocation was finalized during the third quarter of 2018. We have recognized $40.2 million of goodwill as a result of the transaction of which approximately $6 million, including deferred taxes, will be non-deductible for tax purposes. We also incurred acquisition costs of $0.7 million related to this acquisition during the nine months ended September 30, 2017, which was included in general and administrative expense on our condensed consolidated statements of income.

The following table summarizes the consideration and the assets acquired at the Spectrum closing date (in thousands):

Total intangible assets	$	31,900

These intangible assets are amortized on a straight-line basis, which is presented in amortization in our condensed consolidated statements of income. Amortization expense for the intangible assets for the Spectrum acquisition was $0.4 million and $0.1 million for the three months ended September 30, 2018 and 2017, respectively, and $1.3 million and $0.1 million for the nine months ended September 30, 2018 and 2017, respectively.

Repeat Precision

On February 1, 2017, we acquired a 50% interest in Repeat Precision for $6.0 million. Historically, the business had been a supplier to NCS. Our strategic purchase of 50% of this business ensures that we have continued access to these services and allows us greater control of the allocation of their capacity, ensuring that we can scale their operations together with ours. In addition, Repeat Precision also markets composite frac plugs and related products, providing an additional revenue opportunity.

Concurrent with entering into the transaction, the previous owner of the 50% interest repaid a $1.0 million promissory note to us. We also recorded an earn-out at the acquisition date as a contingent adjustment to the purchase price in the amount of $7.0 million. We estimated the fair value of the earn-out using a Monte Carlo simulation on the acquisition date. The earn-out equity value was based on Repeat Precision’s 2018 EBITDA, multiplied by three, which was then reduced by debt and increased by cash. The earn-out equity value was then discounted at the adjusted cost of equity. The earn-out is subject to re-measurement each reporting period using Level 3 inputs until it has been paid. Subsequent changes in the fair value of the liability are reflected in our condensed consolidated statements of income as a change in fair value of contingent consideration. As of September 30, 2018, the earn-out had a value of $9.8 million, which is included in current contingent consideration on the condensed consolidated balance sheet. As of December 31, 2017, the earn-out had a value of $9.4 million, which is included in noncurrent contingent consideration on the condensed consolidated balance sheet. We recognized an expense (benefit) of $0.1 million and $(0.2) million during the three months ended September 30, 2018 and 2017, respectively, and $0.4 million and $0.6 million for the nine months ended September 30, 2018 and 2017, respectively, as a change in fair value of contingent consideration expense in the condensed consolidated statements of income related to the fair value adjustment of the earn-out. The cash payment, if any, is expected to be paid during the first quarter of 2019 and will not exceed $10.0 million.

As NCS has the controlling voting interest in Repeat Precision, we determined that the transaction was a business combination and used the acquisition method of accounting and have included Repeat Precision in our condensed consolidated financial statements from the acquisition date. As a result, the other party’s ownership percentage is presented separately as a non-controlling interest.

The purchase price is allocated to the fair value of assets acquired and liabilities assumed as of the acquisition date and goodwill is recognized for the excess consideration transferred over the fair value of the net assets. By combining Repeat Precision’s expertise in providing high-quality machining services with NCS’s engineering capabilities, product development expertise and customer relationships, we believe that we have additional revenue opportunities for NCS to leverage the vertically integrated supply chain by developing and marketing new completions products. This expected synergy gives rise to goodwill being recorded as part of the purchase price of Repeat. The purchase price allocation was finalized during the first quarter of 2018. We have recognized $15.2 million of goodwill as a result of the transaction and expect the full amount to be deductible for tax purposes. We also incurred acquisition costs of $0.3 million related to this acquisition for the nine months ended September 30, 2017, which was included in general and administrative expense on our condensed consolidated statements of income.

The following table summarizes the consideration and the assets acquired at the Repeat Precision closing date (in thousands):


Consideration

The unaudited pro forma operating results pursuant to ASC 805 related to the Repeat Precision acquisition have been excluded due to immateriality.

In connection with the Repeat Precision acquisition, we acquired intangible assets in the amount of $4.1 million related to customer relationships. The intangible assets are amortized over their estimated ten-year useful lives. Amortization expense for the Repeat Precision acquisition was $0.1 million for each of the three months ended September 30, 2018 and 2017, respectively, and $0.3 million for each of the nine months ended September 30, 2018 and 2017, respectively.

The estimated fair value of total debt for the periods ended September 30, 2018 and December 31, 2017 was $25.0 million and $26.7 million, respectively. The carrying value of the Senior Secured Credit Facility and the lines of credit approximated the fair value of debt as they can be paid at any time. The fair value for the remaining debt was estimated using Level 2 inputs by calculating the sum of the discounted future interest and principal payments through the date of maturity.

Below is a description of our credit agreement and other financing arrangements.

Senior Secured Credit Facility

On May 4, 2017, we entered into an Amended and Restated Credit Agreement (the “Credit Agreement”) with Pioneer Investment, Inc., as borrower (the “U.S. Borrower”), NCS Multistage Inc., as borrower (the “Canadian Borrower”), Pioneer Intermediate, Inc. (together with the Company, the “Parent Guarantors”) and the lenders party thereto, Wells Fargo Bank, National Association as administrative agent in respect of the U.S. Facility (as defined below) and Wells Fargo Bank, National Association, Canadian Branch, as administrative agent in respect of the Canadian Facility (as defined below) (the senior secured revolving credit facilities provided thereunder, the “Senior Secured Credit Facility”). The Credit Agreement amended and restated the prior credit agreement in its entirety. The Senior Secured Credit Facility will mature on May 4, 2020.

The Senior Secured Credit Facility originally consisted of a (i) senior secured revolving credit facility in an aggregate principal amount of $25.0 million made available to the U.S. Borrower (the “U.S. Facility”), of which up to $5.0 million may be made available for letters of credit and up to $5.0 million may be made available for swingline loans and (ii) senior secured revolving credit facility in an aggregate principal amount of $25.0 million made available to the Canadian Borrower (the “Canadian Facility”).

We entered into Amendment No. 1 to the Credit Agreement on August 31, 2017, which increased the loan commitment available to the U.S. Borrower to $50.0 million from $25.0 million under the U.S. Facility. The loan commitment available under the Canadian Facility remained at $25.0 million. On February 16, 2018, we entered into Amendment No. 2 to the Credit Agreement, which amended certain negative covenants contained in the Credit Agreement. As of September 30, 2018 and December 31, 2017, we had $20.0 million in outstanding indebtedness under the U.S. Facility and no outstanding indebtedness under the Canadian Facility.

We incurred interest expense related to the Senior Secured Credit Facility, including commitment fees, of $0.1 million for each of the three months ended September 30, 2018 and 2017, respectively, and $0.9 million and $0.1 million for the nine months ended September 30, 2018 and 2017, respectively.

Borrowings under the U.S. Facility may be made in U.S. dollars, Canadian dollars or Euros and bear interest at a rate equal to the Adjusted Base Rate or Eurocurrency Rate (each as defined in the Credit Agreement), in each case, plus an applicable interest margin as set forth in the Credit Agreement. Borrowings under the Canadian Facility may be made in U.S. dollars or Canadian dollars and bear interest at the Canadian (Cdn) Base Rate, Canadian (U.S.) Base Rate, Eurocurrency Rate or Discount Rate (each as defined in the Credit Agreement), in each case, plus an applicable interest margin as set forth in the Credit Agreement. The Adjusted Base Rate, Canadian (U.S.) Base Rate and Canadian (Cdn) Base Rate applicable margin will be between 2.25% and 3.00% and Eurocurrency Rate applicable margin will be between 3.25% and 4.00%, in each case, depending on the Company’s leverage ratio. The applicable interest rate at September 30, 2018 was 5.50%.

The obligations of the U.S. Borrower under the U.S. Facility are guaranteed by the Parent Guarantors and each of the other existing and future direct and indirect restricted subsidiaries of the Company organized under the laws of the United States (subject to certain exceptions) and are secured by substantially all of the assets of the Parent Guarantors, the U.S. Borrower and such other subsidiary guarantors, in each case, subject to certain exceptions and permitted liens. The obligations of the Canadian Borrower under the Canadian Facility are guaranteed by the Parent Guarantors, the U.S. Borrower and each of the future direct and indirect restricted subsidiaries of the Company organized under the laws of the United States and Canada (subject to certain exceptions) and are secured by substantially all of the assets of the Parent Guarantors, the U.S. Borrower, the Canadian Borrower and such subsidiary guarantors, if any, in each case, subject to certain exceptions and permitted liens.

The Credit Agreement contains financial covenants that require (i) commencing with the fiscal quarter ending June 30, 2017, compliance with a leverage ratio test set at (A) 3.00 to 1.00 as of the last day of each fiscal quarter ending prior to March 31, 2018 and (B) 2.50 to 1.00 as of the last day of each fiscal quarter ending on or after March 31, 2018, (ii) commencing with the fiscal quarter ending June 30, 2017, compliance with an interest coverage ratio test set at 2.75 to 1.00 as of the last day of each fiscal quarter, (iii) if the leverage ratio as of the end of any fiscal quarter is greater than 2.00 to 1.00 and the amount outstanding under the Canadian Facility at any time during such fiscal quarter was greater than $0, compliance as of the end of such fiscal quarter with a Canadian asset coverage ratio test set at 1.00 to 1.00 and (iv) if the leverage ratio as of the end of any fiscal quarter is greater than 2.00 to 1.00 and the amount outstanding under the U.S. Facility at any time during such fiscal quarter was greater than $0, compliance as of the end of such fiscal quarter with a U.S. asset coverage ratio test set at 1.00 to 1.00. As of September 30, 2018, we were in compliance with these financial covenants. The Credit Agreement also contains customary affirmative and negative covenants, including, among other things, restrictions on the creation of liens, the incurrence of indebtedness, investments, dividends and other restricted payments, dispositions and transactions with affiliates. The Credit Agreement also includes customary events of default for facilities of this type (with customary grace periods, as applicable). If an event of default occurs, the lenders under each of the U.S. Facility and the Canadian Facility may elect (after the expiration of any applicable notice or grace periods) to declare all outstanding borrowings under such facility, together with accrued and unpaid interest and other amounts payable thereunder, to be immediately due and payable. The lenders under each of the U.S. Facility and the Canadian Facility also have the right upon an event of default thereunder to terminate any commitments they have to provide further borrowings under such facility. Further, following an event of default under each of the U.S. Facility and the Canadian Facility, the lenders thereunder will have the right to proceed against the collateral granted to them to secure such facility.

Direct costs of $1.0 million were incurred in connection with the Senior Secured Credit Facility. The costs were capitalized as an asset as they represent the benefit of being able to access capital over the contractual term. The costs are being amortized over the term of the Senior Secured Credit Facility using the straight-line method. Amortization expense of the deferred financing charges of $0.1 million for each of the three months ended September 30, 2018 and 2017, respectively, and $0.3 million and $0.1 million was included in interest expense, net for the nine months ended September 30, 2018 and 2017, respectively.

Promissory Note

Commitments and Contingencies [Abstract]
Commitments and Contingencies	Note 9. Commitments and Contingencies Litigation In the ordinary course of our business, from time to time, we have various claims, lawsuits and administrative proceedings that are pending or threatened with respect to commercial, intellectual property and employee matters. On July 24, 2018, we filed a patent infringement lawsuit against Kobold Corporation, Kobold Completions Inc. and 2039974 Alberta Ltd. (“Kobold”) in the Federal Court of Canada, alleging that Kobold’s fracturing tools and methods infringe on several of our Canadian patents. We previously filed a breach of contract lawsuit on March 16, 2018, against Kobold Corporation in the Court of Queen’s Bench of Alberta, alleging breach of a prior settlement agreement. Both of these lawsuits seek unspecified monetary damages and injunctive relief. While the outcome of any legal proceedings cannot be predicted with any certainty, based on a consideration of relevant facts and circumstances, our management currently does not expect that the results of these legal proceedings would have a material adverse effect on our financial position, results of operations or cash flows. On March 3, 2017, we received $0.9 million resulting from an arbitration case that was decided in our favor in February 2017. This was recorded as other income, net in our condensed consolidated statements of income for the nine months ended September 30, 2017.

Share-Based Compensation	9 Months Ended
Share-Based Compensation	Sep. 30, 2018
Share-Based Compensation [Abstract]
Share-Based Compensation	Note 10. Share-Based Compensation During the first quarter of 2018, we granted 582,184 restricted stock units (“RSUs”) at a weighted average grant date fair value of $14.54. Of the RSUs granted, 536,014 will vest and settle ratably over three years on each anniversary of the date of grant and 46,170, which were granted to the nonemployee members of the Board of Directors, will vest on the one year anniversary of the grant date. The RSUs for the members of the Board of Directors settle for shares of common stock on a one-for-one basis within thirty days following the earliest of (i) one year following the termination of the person’s service for any reason other than cause, (ii) a change of control or (iii) the fifth anniversary of the grant date. During the first quarter of 2018, we also granted 156,516 of performance stock unit awards (“PSUs”) with a performance period from January 1, 2018 to December 31, 2020. The fair value of the PSUs of $17.37 was measured using a Monte Carlo simulation on the date the PSUs were granted. The number of PSUs ultimately issued under the program is dependent upon our total shareholder return relative to our performance peer group over a three-year performance period. In no event shall the participant earn more than 200% of the target PSUs. If the actual performance falls below the predefined target, the number of shares vested is reduced. If the actual performance falls below the threshold performance level, no PSUs will vest. The total share-based compensation expense for all awards was $2.9 million and $2.1 million for the three months ended September 30, 2018 and 2017, respectively, and $8.2 million and $3.9 million for the nine months ended September 30, 2018 and 2017, respectively.

Income Taxes	9 Months Ended
Income Taxes	Sep. 30, 2018
Income Taxes [Abstract]
Income Taxes	Note 11. Income Taxes The computation of the annual expected effective tax rate at each interim period requires certain estimates and assumptions including, but not limited to, the expected operating income (or loss) for the year, projections of the proportion of income (or loss) earned and taxed in foreign jurisdictions, permanent and temporary differences and the likelihood of recovering deferred tax assets generated in the current year. The accounting estimates used to compute the provision for income taxes may change as new events occur, more experience is acquired or additional information is obtained. The computation of the annual effective rate would include applicable modifications, which were projected for the year, such as certain book expenses not deductible for tax, tax credits and foreign deemed dividends. We recorded a tax expense of $3.2 million and $0.8 million for the three months ended September 30, 2018 and 2017, respectively. For the three months ended September 30, 2018 and 2017, our effective tax rates were 29.3% and 18.0%, respectively. For the nine months ended September 30, 2018 and 2017, we recorded a tax expense of $3.1 million and $2.0 million, respectively. The effective tax rates for the nine months ended September 30, 2018 and 2017 were 15.7% and 28.2%, respectively. The income tax expense and effective tax rate for the three and nine months ended September 30, 2018 were significantly impacted by the U.S. Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act”) including administrative guidance issued by the Internal Revenue Service on April 2, 2018. This guidance along with other updates resulted in a change to the calculation of the mandatory one-time tax on accumulated earnings of foreign subsidiaries in 2017 and a tax expense (benefit) of $0.5 million and ($2.1) million for the three and nine months ended September 30, 2018, respectively, was recorded in tax expense with a corresponding change in the effective tax rate of 4.5% and (10.6)%, respectively. Additionally, the effective tax rate for the nine months ended September 30, 2018 included a tax benefit of $0.4 million for the tax effect of stock awards. The 2017 Tax Act was signed into law on December 22, 2017. The 2017 Tax Act significantly revised the U.S. corporate income tax by, among other things, lowering the statutory corporate tax rate from 35% to 21%, eliminating certain deductions, imposing a mandatory one-time tax on accumulated earnings of foreign subsidiaries as of 2017, introducing new tax regimes, and changing how foreign earnings are subject to U.S. tax. Our preliminary estimate of the 2017 Tax Act and the remeasurement of our deferred tax assets and liabilities is subject to the finalization of management’s analysis related to certain matters, such as developing interpretations of the provisions of the 2017 Tax Act, changes to certain estimates and the filing of our tax returns. U.S. Treasury regulations, administrative interpretations or court decisions interpreting the 2017 Tax Act may require further adjustments and changes in our estimates. The final determination of the impact of the 2017 Tax Act and the remeasurement of our deferred assets and liabilities will be completed as additional information becomes available, but no later than one year from the enactment of the 2017 Tax Act in accordance with SAB 118. Those adjustments may impact our provision for income taxes in the period in which the adjustments are made. For our calendar year beginning in 2018 we are subject to several provisions of the 2017 Tax Act including computations under Global Intangible Low Taxed Income (“GILTI”) and Foreign Derived Intangible Income (“FDII”). We were able to make a reasonable estimate of the impact of each provision of the 2017 Tax Act on our effective tax rate for the three and nine months ended September 30, 2018. We will continue to refine our provisional estimates for our computations under the GILTI and FDII rules as we gather additional information. ASC 740 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. The impact of an uncertain income tax position on the income tax returns must be recognized at the largest amount that is more-likely-than-not to be required to be recognized upon audit by the relevant taxing authority. This standard also provides guidance on de-recognition, measurement, classification, interest and penalties, accounting for interim periods, disclosure and transition issues with respect to tax positions. We include interest and penalties as a component of other income, net in the condensed consolidated statements of income and recognized $58 thousand and $2 thousand for the nine months ended September 30, 2018 and 2017, respectively.

Basis of Presentation (Policy)	Sep. 30, 2018
Basis of Presentation [Abstract]
Nature of Business	Nature of Business NCS Multistage Holdings, Inc., through its wholly owned subsidiaries and subsidiaries for which we have a controlling voting interest (collectively referred to as the “Company,” “NCS,” “we” or “us”), is primarily engaged in providing engineered products and support services for oil and natural gas well completions and field development strategies. We offer our products and services primarily to exploration and production companies for use in onshore wells. We operate through service facilities principally located in Houston, Midland and Corpus Christi, Texas; Tulsa and Oklahoma City, Oklahoma; and Calgary, Red Deer, Grande Prairie and Estevan, Canada.
Basis of Presentation	Basis of Presentation Our accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), issued by the Securities Exchange Commission (“SEC”) and have not been audited by our independent registered public accounting firm. The Condensed Consolidated Balance Sheet at December 31, 2017 is derived from our audited financial statements. However, certain information and footnote disclosures required by GAAP for complete annual financial statements have been omitted or condensed as permitted by the rules and regulations of the SEC, and, therefore, these interim financial statements should be read in conjunction with our audited financial statements included in our Annual Report on Form 10-K filed with the SEC on March 9, 2018. In the opinion of management, these condensed consolidated financial statements, which have been prepared pursuant to the rules of the SEC and GAAP for interim financial reporting, reflect all adjustments, which consisted only of normal recurring adjustments that were necessary for a fair statement of the interim periods presented. The results of operations for interim periods are not necessarily indicative of those for a full year. All intercompany accounts and transactions have been eliminated for purposes of preparing these condensed consolidated financial statements.
Intangible Assets	Intangible Assets Certain costs incurred in the development of internal-use software applications are capitalized and costs incurred outside of the software application development stage are expensed as incurred. The amounts capitalized are included in intangibles, categorized as internally developed software, and will be amortized on a straight-line basis over the estimated useful life of the software, which is five years. We will begin to amortize internal-use software when it is ready for its intended use.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Pronouncements Adopted in 2018 In June 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-07, Improvements to Nonemployee Share-Based Payment Accounting (Topic 718). The ASU is intended to reduce the cost and complexity and to improve financial reporting for nonemployee share-based payments. The ASU expands the scope of Topic 718 to include share-based payments issued to nonemployees for goods or services. Consequently, the accounting for share-based payments to nonemployees and employees will be substantially aligned. The ASU is for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606, Revenue from Contracts with Customers. We elected to early adopt this ASU effective April 1, 2018. The adoption of this ASU did not have a material impact on our condensed consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business (Topic 805), to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. For public entities, this guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those periods. We adopted ASU 2017-01 effective January 1, 2018, which did not have a material impact on our condensed consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments (Topic 230). The objective of the guidance is to reduce the existing diversity in practice related to the presentation and classification of certain cash receipts and cash payments. The guidance addresses eight specific cash flow issues including but not limited to, debt prepayment or extinguishment costs, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims and proceeds from the settlement of corporate-owned life insurance policies. For public entities, the guidance is effective for financial statements issued for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years and is retrospective for all periods presented. Early adoption is permitted including for interim periods. We adopted ASU 2016-15 effective January 1, 2018, which did not have a material impact on our condensed consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). The new standard is effective for annual reporting periods beginning after December 15, 2017 and early adoption is permitted, however, not before fiscal years beginning after December 15, 2016. Subsequent to ASU 2014-09’s issuance, Topic 606 was amended for FASB updates that changed the effective date as well as addressed certain aspects regarding new revenue standards. The comprehensive new standard supersedes existing revenue recognition guidance and requires revenue to be recognized when promised goods or services are transferred to customers in amounts that reflect the consideration to which entities expect to be entitled in exchange for those goods or services. Adoption of the new rules could affect the timing of revenue recognition for certain transactions. The guidance permits the use of either a full retrospective or modified retrospective transition method. On January 1, 2018, we adopted ASU 2014-09 and its related amendments (collectively known as Accounting Standards Codification “ASC 606”), using the modified retrospective method. We have concluded that the adoption of this ASU did not have a material impact on our condensed consolidated financial statements. See “Note 2. Revenue” for the required disclosures related to the impact of adopting this standard. Pronouncements Not Yet Effective In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40). The ASU aligns the requirements to capitalize implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements to capitalize implementation costs incurred to develop or obtain internal-use software. For public entities, this guidance is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. We are currently evaluating the impact of the adoption of this guidance. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820). The ASU modifies, removes and adds certain disclosure requirements on fair value measurements. For public entities, this guidance is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted for all amendments. Further, entities may early adopt eliminated or modified disclosure requirements and delay the adoption of all new disclosure requirements until the effective date. We are currently evaluating the impact of the adoption of this guidance. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which replaces the existing guidance in ASC 840, Leases. Under ASC 842, lessees will need to recognize most leases on their balance sheets as lease liabilities with corresponding right-of-use assets. The new lease standard also changes the definition of a lease and requires expanded quantitative and qualitative disclosures for both lessees and lessors. Topic 842 was subsequently amended to address certain aspects regarding the new lease standard in addition to offering a new transition method, whereby comparative periods presented in the financial statements in the period of adoption do not need to be restated. Entities are required to adopt ASC 842 using a modified retrospective transition method. Certain practical expedients can be applied. The new standard is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. We plan to adopt ASC 842 effective January 1, 2019 and are currently assessing the impact of the adoption. During the second quarter of 2018, we put in place a team, including a third-party consultant, to execute the transition efforts related to the new guidance. We compiled an initial inventory of lease contracts and initiated lease contract reviews. We continue to take steps to update the lease contract inventory and will proceed through our plan for calculations needed for the balance sheet and income statement as well as evaluate additional changes to our business processes and internal controls. While we cannot currently estimate the quantitative effect that ASC 842 will have on our condensed consolidated financial statements, the adoption of ASC 842 will increase our asset and liability balances on the condensed consolidated balance sheets due to the required recognition of right-of-use assets and corresponding lease liabilities for most lease obligations that are currently classified as operating leases. We also plan to utilize the FASB package of three practical expedients under ASC 842-10-65-1(f).
