Organization and Basis of Presentation [Abstract]
Organization and Basis of Presentation	Note 1. Organization and Basis of Presentation Organization 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. We are a Delaware corporation. We changed our name from Pioneer Super Holdings, Inc. to NCS Multistage Holdings, Inc. on December 13, 2016. Basis of Presentation Our accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). All intercompany transactions have been eliminated in consolidation Initial Public Offering On April 13, 2017, in connection with the initial public offering of shares of our common stock (“IPO”), our board of directors and stockholders approved an amendment to the amended and restated certificate of incorporation effecting a 3.00 for 1.00 stock split of our issued and outstanding shares of common stock. The stock split was implemented on April 13, 2017 and the par value of the common and preferred stock was not adjusted as a result of the stock split. All other common stock share amounts disclosed in this Annual Report on Form 10-K (this “Form 10-K”) have been adjusted to reflect this stock split for all periods presented. In addition, in connection with the IPO, our certificate of incorporation was amended and restated to increase our authorized capital stock to consist of 225.0 million shares of common stock, par value $0.01 per share, and 10.0 million shares of preferred stock, par value $0.01 per share. On May 3, 2017, we completed the initial public offering of 9.5 million shares of our common stock, $0.01 par value, at a price to the public of $17.00 per share pursuant to a Registration Statement on Form S-1, as amended (File No. 333-216580) (the “Registration Statement”). The underwriters exercised their option to purchase an additional 1.425 million shares of our common stock from certain selling stockholders and the closing of the over-allotment option occurred on May 3, 2017, concurrently with the closing of the IPO. We received $148.9 million in net proceeds after deducting underwriting discounts and commissions and other offering expenses of $12.6 million. We used a portion of the net proceeds from the IPO to repay our indebtedness under our Prior Senior Secured Credit Facility (see “Note 8. Debt”). We used the remaining net proceeds from the IPO to acquire Spectrum Tracer Services, LLC, an Oklahoma limited liability company (“Spectrum”), on August 31, 2017.

Summary of Significant Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates include but are not limited to estimated losses on accounts receivables, estimated realizable value on excess and obsolete inventories, estimates related to fair value of reporting units for purposes of assessing possible goodwill impairment, expected future cash flows from long lived assets to support impairment tests, share based compensation, amounts of deferred taxes and income tax contingencies. Actual results could materially differ from those estimates.

Foreign Currency

Our functional currency is the U.S. Dollar (“USD”). The financial position and results of operations of our Canadian subsidiary are measured using the local currency as the functional currency. In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 830, Foreign Currency Matters, revenues and expenses of the subsidiary have been translated into U.S. dollars at average exchange rates prevailing during the period. Assets and liabilities have been translated at the rates of exchange on the consolidated balance sheet date. The resulting translation gain and loss adjustments have been recorded directly as a separate component of other comprehensive (loss) in the accompanying consolidated statements of comprehensive (loss), and changes in stockholders’ equity.

Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in the consolidated statements of operations as incurred.

Revenue Recognition

We recognize revenue when it is determined that the following criteria are met: (i) persuasive evidence of an arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) the fee is fixed or determinable; and (iv) collectability is reasonably assured.

We recognize revenue 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 it does not include right of return or other similar provisions or other significant post-delivery obligations. Revenue is recognized generally for products upon installation and when the customer assumes the risks and rewards of ownership. In cases where services are being performed, we generally do not recognize revenue until a job has been completed, which includes a customer signature or acknowledgement and that there are no additional services or future performance obligation required by us. Rates for services are typically priced on a per day, per man-hour or similar basis that include both the cost of utilizing our downhole frac isolation assembly and our personnel required to supervise the operation of the assembly.

Cash and Cash Equivalents

We consider all highly liquid instruments purchased with an original maturity date of three months or less to be cash equivalents. These items are carried at cost, which approximates fair value.

In accordance with ASC 230, Statements of Cash Flow, cash flows from our Canadian subsidiary are calculated based on our functional currency. As a result, amounts related to changes in assets and liabilities reported in the consolidated statements of cash flows will not necessarily agree to changes in the corresponding balances on the consolidated balance sheets.

Concentration of Credit Risk

Financial instruments that potentially subject us to credit risk are cash and cash equivalents and trade accounts receivable. Cash balances are maintained in financial institutions which, at times, exceed federally insured limits. We monitor the financial condition of the financial institutions in which the accounts are maintained and have not experienced any losses in such accounts.

Substantially all of our sales are to customers whose activities are directly or indirectly related to the oil and gas industry. We generally extend credit to these customers and, therefore, collection of receivables is affected by the oil and gas industry economy. We perform ongoing credit evaluations as to the financial condition of our customers with respect to trade accounts receivables. Generally, no collateral is required as a condition of sale.

For the years ended December 31, 2017, 2016 and 2015, there was one customer that accounted for 10% or more of the total revenue or 10% or more of the total accounts receivable balance at the end of the respective periods. We recognized revenue from this customer totaling $27.4 million, or 14% of 2017 total revenue for the year ended December 31, 2017, $25.5 million, or 26% of 2016 total revenue for the year ended December 31, 2016 and $35.1 million or 31% of 2015 total revenue for the year ended December 31, 2015. Amounts due from this customer included in trade accounts receivable in the accompanying consolidated balance sheets was $2.0 million as of December 31, 2017 and $7.8 million as of December 31, 2016. No other customer individually accounted for 10% or more of our consolidated revenue during 2017, 2016 and 2015 or trade receivable balance as of December 31, 2017 and 2016.

Accounts Receivable, Trade and Allowance for Doubtful Accounts

Trade accounts receivable are recorded at their invoiced amounts and do not bear interest. We perform ongoing credit evaluations of our clients and monitor collections and payments.

We maintain an allowance for doubtful accounts for estimated losses that may result from the inability of our customers to make required payments. Earnings are charged with a provision for doubtful accounts based on a current review of the collectability of customer accounts by management. Such allowances are based upon several factors including, but not limited to credit approval practices, industry and customer historical experience as well as the current and projected financial condition of the specific customer. Accounts deemed uncollectible are applied against the allowance for doubtful accounts. As of December 31, 2017 and 2016, we have recorded $11 thousand and $0.1 million, respectively, in provisions for doubtful accounts.

Inventories

Inventories consist primarily of raw material, sliding sleeves components, assembled sliding sleeves, certain components used to internally construct our frac isolation assemblies and chemicals, in raw material or finished goods, used for frac diagnostics testing and reporting. Inventories are stated at the lower of cost or estimated net realizable value. Cost is determined at standard costs approximating the first-in first-out basis with the exception of chemical costs, which are determined using average costing. We continuously evaluate inventories, based on an analysis of inventory levels, historical sales experience and future sales forecasts, to determine obsolete, slow-moving and excess inventory. Adjustments to reduce such inventory to its estimated recoverable value have been recorded as an adjustment to cost of sales.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Equipment held under capital leases are stated at the present value of minimum lease payments. Expenditures for property and equipment and for items which substantially increase the useful lives of existing assets are capitalized at cost and depreciated over their estimated useful life utilizing the straight-line method. Routine expenditures for repairs and maintenance are expensed as incurred. Depreciation is calculated over the estimated useful lives of the related assets using the straight-line method. Leasehold improvements and property under capital leases are amortized over the shorter of the remaining lease term or useful life of the related asset. Depreciation expense includes amortization of assets under capital leases. The cost and related accumulated depreciation of assets retired or otherwise disposed of are eliminated from the accounts, and any resulting gains or losses are recognized in other (expense) income, net in the year of disposal.

Depreciation on property and equipment, including assets held under capital leases, is calculated using the straight-line method over the following useful service lives or lease term (which includes reasonably assured renewal periods):



	Years
Buildings	30
Building equipment	5-15
Machinery and equipment	5-12
Furniture and fixtures	3-5
Computers and software	3-5
Vehicles and rental equipment	3-4
Leasehold improvements	Lease term (1-4)

We periodically assess potential impairment of our property and equipment, when events or changes in circumstances occur that indicate the carrying value of the asset or asset group may not be recoverable. The assessment of possible impairment is based on our overall valuation calculation using forward looking as well as historical computations to measure the value of our long-lived assets. If the overall valuation results are less than the carrying value of such assets, an impairment loss is recognized for the difference between estimated fair value and carrying value. No impairment loss has been recognized for the years ended December 31, 2017, 2016 and 2015.

Business Combinations, Goodwill and Intangible Assets

Business combinations are accounted for under the acquisition method of accounting in accordance with FASB ASC 805, Business Combinations. Under the acquisition method of accounting, the total consideration transferred in connection with the acquisition is allocated to the tangible and intangible assets acquired, liabilities assumed, and any non-controlling interest in the acquiree based on their fair values. Goodwill acquired in connection with business combinations represents the excess of consideration transferred over the net tangible and identifiable intangible assets acquired. Certain assumptions and estimates are employed in evaluating the fair value of assets acquired and liabilities assumed. These estimates may be affected by factors such as changing market conditions, technological advances in the oil and natural gas industry or changes in regulations governing that industry. The most significant assumptions requiring judgment involve identifying and estimating the fair value of intangible assets and the associated useful lives for establishing amortization periods. To finalize purchase accounting for significant acquisitions, we utilize the services of independent valuation specialists to assist in the determination of the fair value of acquired intangible assets.

Costs related to the acquisition, other than those associated with the issuance of debt or equity securities, that we incur in connection with a business combination are expensed as incurred.

Any contingent consideration payable is recognized at fair value at the acquisition date. Liability-classified contingent consideration is remeasured each reporting period with changes in fair value recognized in earnings until the contingent consideration is settled.

For goodwill, an assessment for impairment is performed annually or, more frequently, when there is an indication an impairment may have occurred. We complete our annual impairment test for goodwill using an assessment date in the fourth quarter of each fiscal year. Goodwill is reviewed for impairment by comparing the carrying value of the reporting unit’s net assets (including allocated goodwill) to the fair value of the reporting unit. The fair value of the reporting unit is determined using a discounted cash flow approach. Determining the fair value of a reporting unit requires the use of estimates and assumptions. The principal estimates and assumptions that we use include revenue growth rates, operating margins, weighted average costs of capital, a terminal growth rate, and future market conditions. We believe that the estimates and assumptions used in impairment assessments are reasonable.

All identifiable intangibles are amortized on a straight-line basis over the estimated useful life or term of related agreements. Deferred loan costs are amortized to interest expense using the effective interest method. These assets are tested for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable.

We concluded that there was no impairment of goodwill or identifiable assets for the years ended December 31, 2017, 2016 or 2015.

Income Taxes

NCS Multistage Holdings, Inc. is taxed as a corporation as defined under the Internal Revenue Code. The liability method is used in accounting for deferred income taxes. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when these differences are expected to reverse. The realizability of deferred tax assets are evaluated annually and a valuation allowance is provided if it is more likely than not that the deferred tax assets will not give rise to future benefits. We follow guidance in ASC 740 “Income Taxes” for uncertainty in income taxes by prescribing the minimum recognition threshold an income tax position is required to meet before being recognized in the consolidated financial statements and applies to all income tax positions. Each income tax position is assessed using a two-step process. A determination is first made as to whether it is more likely than not that the income tax position will be sustained, based upon technical merits, upon examination by the taxing authorities. If the income tax position is expected to meet the more likely than not criteria, the benefit recorded in the consolidated financial statements equals the largest amount that is greater than 50% likely to be realized upon its ultimate settlement. A valuation allowance to reduce deferred tax assets is established when is more likely than not that some portion or all the deferred tax assets will not be realized. As of December 31, 2017 and 2016, our valuation allowance was $18 thousand and $63 thousand, respectively. We recognize accrued interest and penalties related to uncertain tax positions in other income (expense) on the statements of operations. During the years ended December 31, 2017, 2016 and 2015, respectively, we recognized $0.2 million, $0.1 million and $0.1 million in interest and penalties. We had $0.6 million and $0.4 million in interest and penalties accrued at December 31, 2017 and 2016, respectively.

We completed our analysis of our tax positions and believe there are no material uncertain tax positions that would require recognition in the consolidated financial statements as of December 31, 2017 and 2016. We believe that there are no tax positions taken or expected to be taken as of December 31, 2017 and 2016 that would significantly increase or decrease unrecognized tax benefits within the next twelve months following the balance sheet date. As of December 31, 2017 and 2016, there were no material amounts that had been accrued with respect to uncertain tax positions.

One of our Canadian subsidiaries guaranteed the credit facilities of our U.S. entities until May 2017 when cash proceeds were received from the IPO, a portion of which was used to pay off the existing debt. Under U.S. federal income tax rules, this guarantee resulted in all of the earnings and profits of our Canadian subsidiary being subject to current U.S. tax. As a result of the 2017 Tax Act and a change in our permanent earnings reinvestment assertion, we have recognized a $3.9 million U.S. tax benefit for the reversal of our deferred tax liability on a portion of our differences between book value and tax basis in our Canadian subsidiary for which we are now asserting indefinite reinvestment. Therefore, as of December 31, 2017 no U.S. deferred tax liabilities have been recognized on the differences between book value and tax basis that we continue to indefinitely reinvest. As of December 31, 2016, we have recognized a U.S. deferred tax liability of $3.9 related to a portion of our book value and tax basis differences in our Canadian subsidiary for which we are unable to assert indefinite reinvestment.

No U.S. deferred taxes have been recognized on $91.3 million and $52.1 million as of December 31, 2017 and 2016, respectively, of our book value and tax basis differences that we continue to indefinitely reinvest. Upon reversal of these book value and tax basis differences through dividends or otherwise, we may be subject to foreign withholding taxes. It is not practical, however, to estimate the amount of taxes that may be payable on the eventual remittance of these temporary differences after consideration of available foreign tax credits.

We file income tax returns in the U.S., Canada and various state and foreign jurisdictions. Our U.S. income tax returns for 2011 and subsequent years remain open for examination. The Internal Revenue Service (“IRS”) commenced an examination of our U.S. income tax returns for 2011 through 2012 in the first quarter of 2014 which was completed in 2015. No tax adjustments were proposed. Additionally, the IRS commenced an examination of our U.S. income tax return for 2014 in the second quarter of 2016 which was completed in the second quarter of 2017. No tax adjustments were proposed.

Share-Based Compensation

We account for our stock-based compensation awards in accordance with ASC Topic 718, Compensation—Stock Compensation (“ASC 718”). We measure all share-based compensation awards at fair value on the date they are granted and recognize the compensation expense in the financial statements over the requisite period. We record forfeitures as they occur. Fair value of the share-based compensation was measured using the market price of the common stock for restricted stock units and the Black-Scholes model for options. We also have an employee stock purchase plan, which allows eligible employees to purchase shares of our common stock. The purchase price of the stock will be 85% of the lower of the stock price at the beginning or end of the plan period. The fair value of the employees’ purchase rights under the employee stock purchase plan will also be estimated using the Black-Scholes model. The Black-Scholes model for both options and the shares purchased under the employee stock purchase plan requires assumptions and estimates that affect the resultant values and hence the amount of compensation recognized. These assumptions include our stock price, expected stock price volatility over the term of the awards, expected term, risk free interest rate and expected dividends. Prior to our IPO, we were a private company. Therefore, we estimated our expected stock volatility based on the historical volatility of a publicly traded set of peer companies and expect to continue to do so until such time as we have adequate historical data regarding the volatility of our own traded stock price.

Shipping and Handling Fees and Cost

Shipping and handling fees, if billed to customers, are included in revenues. Shipping and handling costs are classified as cost of revenues.

Fair Value

The carrying amounts for financial instruments classified as current assets and current liabilities approximate fair value, due to the short maturity of such instruments. The book values of other financial instruments, such as our debt under our Senior Credit Facility, approximates fair value because interest rates charged are similar to other financial instruments with similar terms and maturities and the rates vary in accordance with a market index in accordance with ASC 820—Fair Value measurement.

For the financial assets and liabilities disclosed at fair value, fair value is determined as the exit price, or the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The established fair value hierarchy divides fair value measurement into three broad levels:

Level 1—inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date;

Level 2—inputs other than quoted prices included within Level 1 that are observable for the assets or liability, either directly or indirectly; and

Level 3—inputs are unobservable for the asset or liability, which reflect the best judgment of management.

The financial assets and liabilities that are disclosed at fair value for disclosure purposes are categorized in one of the above three levels based on the lowest level input that is significant to the fair value measurement in its entirety. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment. For additional information on our Level 3 liabilities, see “Note 3. Acquisitions.”

Earnings Per Share

Basic income per share is calculated by dividing net income (loss) attributable to NCS Multistage Holdings, Inc., reduced for the allocation of net income (loss) attributable to participating security holders of exchangeable securities held in our indirect subsidiary, by the weighted-average number of common shares outstanding during the period. The participating security holders were allocated 4.2%, 0.0% and 5.7% of the net income for December 31, 2017, 2016 and 2015, respectively. The participating security holders are not contractually obligated to share in our losses, therefore, losses are not allocated to the participating security holders. The diluted income per share computation is calculated by dividing net income (loss) attributable to NCS Multistage Holdings, Inc. by the weighted-average number of common shares outstanding during the period, taking into effect, if any, of shares that would be issuable upon the exercise of outstanding stock options, unvested restricted stock units, purchases under the employee stock purchase plan and conversion of the participating security holders exchangeable securities, reduced by the number of shares purchased by us at cost, when such amounts are dilutive to the income per share calculation.

Research and Development

Research and development (“R&D”) costs are incurred both through engaging third parties to perform development activities under our coordination and management as well as through the utilization of our employees to create and develop new ideas and product. We incurred approximately $3.0 million, $3.3 million and $3.0 million in R&D costs for the years ended December 31, 2017, 2016 and 2015, respectively. These costs are recorded in selling, general and administrative expense on the consolidated statements of operations.

Recent Accounting Pronouncements

Pronouncements Adopted in 2017

In May 2017, the FASB issued Accounting Standards Update (“ASU”) No. 2017-09, Scope of Modification Accounting (Topic 718), which clarifies when to account for a change to the terms and conditions of a share-based payment award as a modification. Under the new guidance, an entity should apply modification accounting unless the modified award has the same fair value, vesting conditions, and classification of equity or liability as the original award. We have elected to early adopt this ASU in the second quarter of 2017. The adoption of this ASU had no material impact on our consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Accounting for Goodwill Impairment (Topic 350). This new standard simplifies the test for goodwill impairment. In the original guidance, an entity is required to perform additional analysis in Step 2, which measures a goodwill impairment loss by comparing the implied fair value of a report unit’s goodwill with the carrying amount of that goodwill. The FASB simplifies the subsequent measurement of goodwill by eliminating Step 2. Instead, under the amendments in this update, an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount with excess carrying value over the fair value recognized as a loss on impairment. In addition, income tax effects from any tax deductible goodwill are considered in measuring the goodwill impairment loss, if applicable. The amendments in this update are effective for public companies for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2020, with early adoption permitted. We adopted the guidance in ASU 2017-04 effective April 1, 2017.

In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (Topic 718), to simplify the accounting for share-based payment transactions, including accounting for forfeitures, excess tax benefit/expense, and tax withholding requirements. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 31, 2016. We adopted this guidance on January 1, 2017 and have elected to recognize actual forfeitures when they occur. The adoption did not have a material impact on our consolidated financial statements.

In November 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes (Topic 740). This standard requires all deferred taxes, along with any related valuation allowance, to be presented as a noncurrent deferred asset or liability. The guidance is effective for fiscal years beginning after December 15, 2016, and includes interim periods within those fiscal years. Early adoption is permitted and the guidance may be applied either prospectively, for all deferred tax assets and liabilities, or retrospectively by reclassifying the comparative balance sheet. We adopted this ASU in the first quarter of 2017 on a prospective basis.

Pronouncements Not Yet Effective

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 will be effective for annual periods beginning after December 15, 2017, including interim periods within those periods. We will adopt ASU 2017-01 on January 1, 2018 and do not expect to have a material impact on our 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 will adopt ASU 2016-15 on January 1, 2018 and do not expect to have a material impact on our consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which replaces the existing guidance in ASC 840, Leases. ASC 842 requires lessees to recognize most leases on their balance sheets as lease liabilities with corresponding right-of-use assets. The new lease standard does not substantially change lessor accounting. The new standard is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the impact of the adoption of this guidance.

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 will supersede existing revenue recognition guidance and require 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. We put in place a team during the second quarter of 2017, including a third-party consultant, to assess the impacts of the new standard and to develop and carry out our implementation plan. The team reviewed our revenue streams and compared our historical accounting policies and practices to the new accounting guidance. The review also included our acquisitions of Spectrum and Repeat Precision, LLC (“Repeat Precision”). Based upon the analysis, we will adopt and apply the modified retrospective method of transition on January 1, 2018. We have concluded that the adoption of this ASU will not have a material impact on our consolidated financial statements.

Acquisitions [Abstract]

Acquisitions

Note 3. Acquisitions

Spectrum Tracer Services

On August 31, 2017, we acquired 100% of the equity interests in 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. We believe Spectrum’s tracer diagnostics services 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 and is included in contingent consideration on the balance sheet. We estimated the fair value of the earn-out using a Black-Scholes closed form option pricing model. The earn-out is subject to re-measurement each reporting period using Level 3 inputs until the full amount of the liability has been satisfied. Subsequent changes in the fair value of the liability are reflected in our consolidated statements of operations as a change in fair value of contingent consideration. As of December 31, 2017, the earn-out had a value of $3.4 million. During the year ended December 31, 2017, we recognized $3.0 million as a change in fair value of contingent consideration expense in the consolidated statements of operations related to the change in fair value of the Spectrum earn-out. The cash payment, if any, is expected to be paid during the second quarter of 2019.

Spectrum contributed revenues of $12.8 million and net income of $0.3 million to us for the period from September 1, 2017 to December 31, 2017. The net income included a one-time charge of $0.4 million of income tax expense related to the U.S. transition tax on its unremitted foreign earnings. 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 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)
	Year Ended December 31,
	2017		2016
Revenue	$	220,478	$	117,211
Net income (loss) attributable to NCS Multistage Holdings, Inc.	$	1,664	$	(19,442)
Diluted earnings (loss) per share	$	0.04	$	(0.57)

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. The assets and liabilities of Spectrum have been measured based on various preliminary estimates using assumptions that we believe are reasonable based on information that is currently available. The purchase price allocation is preliminary and adjustments to provisional amounts may occur as we continue to analyze information. We have recognized $40.2 million of goodwill as a result of the transaction of which approximately $6 million will be non-deductible for tax purposes. Additional changes to the purchase price allocation may result in a corresponding change to goodwill in the period of the change, however, we do not expect such adjustments to materially change the purchase price allocation. We also incurred acquisition costs of $0.7 million and $1.0 million during the years ended December 31, 2017 and 2016, respectively, which were included in general and administrative expense on our consolidated statements of operations.

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


Consideration
Cash consideration	$	76,485
Equity consideration		6,907
Earn-out liability recognized		352
Total consideration	$	83,744

The amount allocated to intangible assets was attributed to the following categories (in thousands):


			Estimated Useful
	Fair Value		Lives (Years)
Technology	$	5,600	16
Trademarks		1,600	10
Customer relationships		24,700	21
Total intangible assets	$	31,900

These intangible assets are amortized on a straight-line basis, which is presented in amortization in our consolidated statements of operations. Amortization expense for the intangible assets for the Spectrum acquisition was $0.6 million for the year ended December 31, 2017.

Repeat Precision

On February 1, 2017, we acquired a 50% interest in Repeat Precision for $6.0 million. Historically, the business has 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 certain completion products on a wholesale basis, 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, which was included in contingent consideration on the balance sheet. 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 the full amount of the liability has been satisfied. Subsequent changes in the fair value of the liability are reflected in our consolidated statements of operations as a change in fair value of contingent consideration. As of December 31, 2017, the earn-out had a value of $9.4 million. During the year ended December 31, 2017, we recognized $2.5 million as a change in fair value of contingent consideration expense in the consolidated statements of operations related to the change in fair value 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 the joint venture, we determined that the transaction was a business combination and used the acquisition method of accounting and have included Repeat Precision in our 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. The purchase price allocation is preliminary and adjustments to the working capital provisional amounts may continue to occur as we analyze information. 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. Additional changes to the purchase price allocation may result in a corresponding change to goodwill in the period of the change, however, we do not expect such adjustments to materially change the purchase price allocation. We also incurred acquisition costs of $0.3 million during the first quarter of 2017, which were included in general and administrative expense on our consolidated statements of operations.

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


Consideration
Cash paid by NCS	$	5,996
Earn-out liability recognized		6,958
Total consideration	$	12,954
Preliminary purchase price allocation
Other net assets	$	174
Inventory		662
Property and equipment		5,750
Intangible assets		4,100
Goodwill		15,222
Total assets acquired	$	25,908
Less: non-controlling interest		(12,954)
Net assets acquired	$	12,954

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 intangible assets for the Repeat Precision acquisition was $0.4 million for the year ended December 31, 2017.

The estimated fair value of total debt for the periods ended December 31, 2017 and December 31, 2016 was $26.7 million and $92.8 million, respectively. The carrying value of the Senior Secured Revolving Credit Facility as of December 31, 2017 approximated the fair value of debt as it can be paid at any time. The fair value 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 prior and new credit agreements and other financing arrangements.

Prior Senior Secured Credit Facility

Effective August 7, 2014, we entered into a credit agreement (the “Prior Credit Agreement”) with a group of financial institutions which was denominated in Canadian dollars (“CAD”) and allowed for a term loan of up to $197.6 million CAD ($180.0 million USD), and a $38.4 million CAD ($35.0 million USD) revolving line of credit of which $5.0 million CAD was available for letters of credit and $5.0 million CAD was available for swingline loans (together, the “Prior Credit Facility”). We entered into Amendment No. 1, effective April 15, 2015, and Amendment No. 2, effective December 22, 2015, which modified the original credit agreement governing the Prior Credit Facility. The modifications changed various defined terms as well as the covenants. These amendments also revised the revolving credit commitment to $27.8 million CAD ($20.0 million USD) and evidenced the prepayment of the Prior Term Loan in an amount of $55.8 million CAD.

The term loan accrued interest at the adjusted base rate or Canadian base rate plus an applicable margin, as defined in the credit agreement governing the Prior Credit Facility, with quarterly interest payments. The term loan was collateralized by certain assets of the Company and guaranteed by certain wholly owned subsidiaries of the Company. The interest on the term loan was payable in quarterly installments. All unpaid principal and interest was scheduled to mature on August 7, 2019. As of December 31, 2016, the term loan had an outstanding balance of $90.8 million. We incurred interest expense of $1.7 million and $5.5 million for the years ended December 31, 2017 and 2016, respectively.

The revolving line of credit was collateralized by certain assets of the Company and guaranteed by certain wholly owned subsidiaries of the Company. Interest on the revolving line of credit was payable quarterly at the adjusted base rate or Canadian base rate plus an applicable margin, as defined in the agreement governing the Prior Credit Facility.

Direct costs incurred in connection with the term loan were capitalized and amortized over the term of the debt using the effective interest method. Net fees attributable to the lenders of $1.7 million were presented as a discount to the carrying value of debt as of December 31, 2016. As a result of the payment of the loan in full on May 4, 2017, we expensed the remainder of the deferred loan costs of $1.4 million as a component of interest expense, net in the consolidated statements of operations.

In February 2017, to ensure compliance with non-financial covenants per the Prior Credit Facility, we made a $3.0 million term loan prepayment. On May 4, 2017, the term loan was paid in full and terminated using a portion of the proceeds from our IPO and we also entered into a new Amended and Restated Credit Agreement (the “Credit Agreement”).

Senior Secured Credit Facility

On May 4, 2017, we entered into an Amended and Restated 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 (the “Amendment”). The Amendment 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. At December 31, 2017, we had $20.0 million in outstanding indebtedness under the U.S. Facility. We incurred interest expense related to the Senior Secured Credit Facility of $0.4 million for the year ended December 31, 2017.

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 December 31, 2017 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, 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. 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. As of December 31, 2017, we were in compliance with these financial covenants. 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 credit facilities using the straight-line method. Amortization expense of the deferred financing charges of $0.2 million was included in interest expense, net for the year ended December 31, 2017.

Promissory Note

On February 27, 2017, Repeat Precision entered into a promissory note with Security State Bank & Trust, Fredericksburg, for an aggregate borrowing capacity of $3.8 million. The promissory note is secured against equipment, inventory and receivables. It bears interest at a variable interest rate based on prime plus 1% and matures on February 27, 2018. Any principal amount not paid by the maturity date bears interest at the lesser of the maximum rate allowed per law or 18% per annum. As of December 31, 2017, the outstanding balance on the promissory note was $3.3 million.

Equipment Notes

In February 2017, Repeat Precision entered into an equipment note in the amount of $0.8 million with Security State Bank & Trust, Fredericksburg. The equipment note bears interest at prime plus 1%, matures on February 27, 2021 and is collateralized by certain property. Any principal amount not paid by the maturity date bears interest at the lesser of the maximum rate allowed per law or 18% per annum. As of December 31, 2017, the outstanding balance on the equipment note was $0.6 million.

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 and employee matters.

Our management currently does not expect that the results of any of these legal proceedings, either individually or in the aggregate, 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 (expense), net in our consolidated statements of operations for the year ended December 31, 2017.

Operating Leases

We have entered into certain operating lease commitments for buildings and office equipment, which expire at various dates through December 2022.

Stockholders' Equity	12 Months Ended
Stockholders' Equity	Dec. 31, 2017
Stockholders' Equity [Abstract]
Stockholders' Equity	Note 10. Stockholders’ Equity As disclosed in “Note 1. Basis of Presentation”, on April 13, 2017 our board of directors (“Board”) and stockholders approved an amendment to the amended and restated certificate of incorporation effecting a 3.00 for 1.00 stock split of our issued and outstanding shares of common stock. The stock split was implemented on April 13, 2017. The par value of the common and preferred stock was not adjusted as a result of the stock split. All other issued and outstanding shares and per share amounts included in the accompanying consolidated financial statements have been adjusted to reflect this stock split for all periods presented. We currently have common stock and preferred stock outstanding. On April 27, 2017, our certificate of incorporation was amended and restated and the number of shares of common stock authorized to be issued by us was increased from 54,000,000 to 225,000,000 and the number of our authorized shares of preferred stock was increased from one share to 10,000,000 shares. As of December 31, 2017 and 2016, 43,913,136 and 34,005,978 shares of common stock were outstanding, respectively. Additionally, one share of preferred stock, designated as the “Special Voting Share” in our amended and restated certificate of incorporation, was issued and outstanding as of December 31, 2017 and December 31, 2016. The holders of common stock are entitled to one vote for each share of common stock held. The holder of the Special Voting Share shall be entitled to vote on all matters that a holder of common stock is entitled to vote on and shall be entitled to cast a number of votes equal to the number of exchangeable shares of NCS Multistage, Inc. (“NCS Canada”), a subsidiary of the Company, then outstanding that are not owned by us, multiplied by the exchange ratio (as defined in the articles of incorporation of NCS Canada). In connection with our stock split, the exchange ratio was adjusted to three from one. As of December 31, 2016, the number of shares of common stock issuable for the exchangeable shares totaled 1,819,247 and was held by the preferred stockholder. On May 3, 2017, the preferred stockholder sold shares of our common stock in our initial public offering, which reduced the number of shares of common stock issuable for the exchangeable shares. As of December 31, 2017, the number of shares of common stock issuable for the exchangeable shares totaled 1,769,247. The exchangeable shares are convertible upon demand at the stock price on the conversion date. The holders of common stock are entitled to receive dividends as declared from time-to-time by our board of directors. The holder of the Special Voting Share is not entitled to receive dividends. No dividends were declared during the periods ended December 31, 2017 or December 31, 2016.

Equity Incentive Plans

We maintain three equity incentive plans for the benefit of our employees, directors and other service providers: our 2011 Equity Incentive Plan (the “2011 Plan”), our 2012 Equity Incentive Plan (the “2012 Plan”) and our 2017 Equity Incentive Plan (the “2017 Plan”). The following is a summary of certain features of the 2011 Plan, 2012 Plan and the 2017 Plan.

2011 Plan

The 2011 Plan provided awards to employees, directors and consultants of NCS Energy Holdings, LLC. In connection with Advent’s acquisition on December 20, 2012, we assumed the options under the 2011 Plan and converted them into options to purchase shares of our common stock. There remains 649,047 options outstanding and exercisable that were granted pursuant to the 2011 Plan as of December 31, 2017.

2012 Plan

The 2012 Plan provided awards to our employees, directors and consultants prior to our IPO. We no longer grant awards under the 2012 Plan. The 2012 Plan is administered by the Compensation, Nominating and Governance Committee of our Board. The 2012 Plan has a total of 2,463,501 shares authorized for issuance. Awards granted under the 2012 Plan will remain outstanding until the earlier of exercise, forfeiture, cancellation or expiration. There remains 2,462,001 options outstanding and 934,323 options exercisable that were granted pursuant to the 2012 Plan as of December 31, 2017.

2017 Plan

The 2017 Plan was adopted in connection with our IPO and provides for awards of stock options, stock appreciation rights, restricted stock awards, restricted stock units, stock awards and performance awards. Awards under the 2017 Plan may be granted to any employee, non-employee director, consultant or other personal service provider to us or any of our subsidiaries. The 2017 Plan is administered by a plan administrator, which is the Compensation, Nominating and Governance Committee or such other committee of the Board or the Board as a whole, in each case as determined by the Board. The 2017 Plan was established with the authorization for grants of up to of 4,532,523 shares of authorized but unissued shares of common stock. As of December 31, 2017, the total number of shares available for future issuance under the 2017 Plan is 4,352,382.

Stock Options

Stock options granted under the 2012 Plan and the 2017 Plan generally vest annually in equal increments over three or five years and have a 10-year term. Before our IPO, we issued certain stock options that were to vest only in connection with a change of control (the “Liquidity Options”). In connection with the IPO, the Liquidity Options were amended for 22 employees to provide that such awards will vest in three equal installments on each of the first three anniversaries of the consummation of our IPO, which occurred on May 3, 2017, subject to certain requirements including, as applicable, the recipient’s continued employment on the vesting date. The modified Liquidity Options are still subject to accelerated vesting upon a company sale, as defined in our 2012 Equity Incentive Plan.

We estimate the fair value of each option grant using the Black-Scholes option-pricing model. The Black-Scholes option pricing model requires estimates of key assumptions based on both historical information and management judgment regarding market factors and trends. Determining the appropriate fair value model and calculating the fair value of options requires the input of highly subjective assumptions, including the expected volatility of the price of our stock, the risk-free rate, the expected term of the options and the expected dividend yield of our common stock. Prior to our IPO, we were a private company. Therefore, we estimated our expected stock volatility based on the historical volatility of a publicly traded set of peer companies and expect to continue to do so until such time as we have adequate historical data regarding the volatility of our own traded stock price. These estimates involve inherent uncertainties and the application of management’s judgment. If factors change and different assumptions are used, our share-based compensation expense could be materially different in the future.

The weighted average assumptions used to estimate the fair value of stock options granted in 2017, 2016 and 2015 are as follows:


	Year Ended December 31,
	2017		2016		2015
Expected volatility	44.4	%	42-44.7	%	43.0	%
Average risk free interest rate	2.0	%	1.7	%	2.3	%
Expected term (in years)	6.0		6.5		6.5
Expected dividends	—	%	—	%	—	%

As a result of the modification of the terms of the Liquidity Options, we estimated the fair value of the Liquidity Options on April 27, 2017, the amendment date, using the Black-Scholes option-pricing model. The total unamortized compensation expense was valued at $17.2 million at April 27, 2017, the amendment date, compared to $10.1 million at December 31, 2016. The weighted average assumptions used to estimate the fair value of the Liquidity Options were as follows:


Expected volatility	44.4	%
Average risk free interest rate	1.7	%
Expected term (in years)	4.6
Expected dividends	—	%

The following table summarizes stock option activity during the years ended December 31, 2017, 2016, and 2015:

The weighted average grant-date fair value of service-based option awards granted during the years 2017, 2016, and 2015 was $7.61, $4.58 and $6.62, respectively. The weighted average grant-date fair value of the Liquidity Options at the amendment date of April 27, 2017 was $11.69. Aggregate intrinsic value represents the difference between our estimated fair value of common stock and the exercise price of outstanding in the money options. As of December 31, 2017, our outstanding, unvested and exercisable aggregate intrinsic values were $21.2 million, $12.9 million and $8.3 million, respectively. The total intrinsic value of options exercised during the years ended December 31, 2017 was $14 thousand. No shares were exercised during the years ended December 31, 2016 and 2015.

Restricted Stock Units

Upon completion of our IPO and pursuant to the 2017 Plan, we began granting restricted stock units (“RSUs”). We account for RSUs granted to employees at fair value on the date of grant, which we measure as the closing price of our stock on the date of grant, and recognize the compensation expense in the financial statements over the requisite service period. Currently outstanding RSUs generally vest over a period of one or three years from the date of grant.

The following is a summary of RSU activity under the 2017 Plan:


	Number of Awards	Weighted Average Grant Date Fair Value
Non-vested at December 31, 2016	—	$	—
Granted	167,494		18.78
Non-vested at December 31, 2017	167,494	$	18.78

Employee Stock Purchase Plan

On August 3, 2017, our board of directors adopted our Employee Stock Purchase Plan (the “U.S. ESPP”) and an employee stock purchase plan specifically applicable to non-U.S. employees on substantially the same terms as the ESPP (the “Non-U.S. ESPP” and together with the U.S. ESPP, the “ESPP”). There are an aggregate of 2,000,000 shares of our common stock reserved for issuance and sale pursuant to the ESPP. The first offering period under our ESPP began on October 16, 2017 and ends on December 31, 2018. We believe future offering periods will span a calendar year. The ESPP allows eligible employees to contribute, subject to any other plan limitations, up to 18% of their base salary, up to a maximum of $25 thousand per calendar year ($50 thousand for the first offering period), toward the purchase of our common stock at a discounted price. The purchase price of the shares on each purchase date is equal to 85% of the lower of the fair market value of our common stock on the first and last trading days of each offering period. The U.S. ESPP is designed to be qualified under Section 423 of the Internal Revenue Code.

The fair value of the ESPP was estimated using the Black-Scholes model with the following assumptions and resulting weighted-average fair value per share:


	Year Ended

All eligible employees may contribute a percentage of their compensation subject to a maximum imposed by the Internal Revenue Code. All of our contributions are discretionary. We suspended the matching program on April 30, 2015 but reinitiated it on January 1, 2016. Similarly, our Canadian employees are eligible to participate in the Group Registered Retirement Savings Program. All eligible employees may make tax deferred contributions to the plan. This matching program was also suspended on April 30, 2015 until January 1, 2016. Contributions made on behalf of Canadian employees by NCS are taxable income to the employee and may not exceed the Canadian Revenue Agency’s deduction limit for the given year. Our contributions were $0.8 million for the year ended December 31, 2017 and $0.6 million for each of the years ended December 31, 2016 and 2015, respectively.

The following is a summary of the items that caused recorded income taxes to differ from income taxes computed using the statutory federal income tax rate for the years ended December 31, 2017, 2016 and 2015:


	Year Ended December 31,

Other		4.4%		0.0%		0.0%
Income tax		34.1%		33.0%		(137.5)%

We recorded a tax expense (benefit) of $0.7 million, $(8.8) million and $(16.2) million for the years ended December 31, 2017, 2016 and 2015, respectively. For the years ended December 31, 2017, 2016 and 2015, our effective tax rate was 34.1%, 33.0% and (137.5%). The primary differences between these effective tax rates were due to several offsetting items, including the effects of recording tax expense for the 2017 Tax Act of $3.9 million, not providing U.S. income taxes on the undistributed earnings of foreign subsidiaries because we intend to permanently reinvest such earnings outside the U.S. and a tax benefit for the reversal of our deferred tax liability due to the change in our foreign unremitted earnings assertion of $3.9 million. During the first quarter of 2017, we changed our assertion to state that undistributed foreign earnings are indefinitely or permanently reinvested as a result of cash proceeds received from the IPO during May 2017, a portion of which was used to pay off existing debt. The negative effective tax rate in 2015 was primarily due to a tax planning strategy and the effect of an adjustment of our deferred taxes liability on differences between book value and tax basis in our Canadian subsidiary. The tax planning strategy resulted in the Company receiving permission from a foreign tax authority to change the year end to conform to U.S. income tax reporting

The 2017 Tax Act was signed into law on December 22, 2017. The 2017 Tax Act significantly revises 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. We recorded a tax benefit of $0.5 million for the remeasurement of federal net deferred tax liabilities resulting from the permanent reduction in the U.S. statutory corporate tax rate to 21% from 35% and recorded a mandatory one-time tax on the accumulated earnings of our foreign subsidiaries of $4.4 million. 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 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.

The tax effects of temporary differences that give rise to significant portions of deferred tax assets and deferred tax liabilities as of December 31, 2017 and 2016 are as follows (in thousands):

Note 1. Background and basis of presentation

NCS Multistage Holdings, Inc. (the “Parent Company”) is a holding company that conducts substantially all of its business operations through its subsidiaries. The ability of the Parent Company’s subsidiaries to pay dividends is currently restricted by the terms of its credit agreement with a group of financial institutions. Substantially all of the net assets of the Parent Company’s consolidated subsidiaries are restricted.

The accompanying condensed financial information includes the accounts of the Parent Company and, on an equity method basis, its investment in subsidiaries. Accordingly, these condensed financial statements have been presented on a “parent only” basis. These parent only financial statements should be read in conjunction with NCS Multistage Holdings, Inc. consolidated financial statements and related notes thereto included elsewhere herein.

The condensed parent-only financial statements have been prepared in accordance with Rule 12-04, Schedule I of Regulation S-X as the restricted net assets of the subsidiaries of the Parent Company exceeds 25% of the consolidated net assets of the Parent Company. The ability of the Parent Company’s operating subsidiaries to pay dividends may be restricted due to terms of the subsidiaries financing arrangements (see “Note 8. Debt” of our consolidated financial statements).

Note 2. Related Party Transactions

As of December 31, 2016, the Company held a long-term note receivable in the amount of $0.8 million due from a related party. During the first quarter of 2017, the long-term note receivable was paid in full.
