Summary of Significant Accounting Policies | Note 2. Summary of Significant Accounting Policies Use of Estimates The preparation of consolidated financial statements in conformity with 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 significant foreign subsidiaries are generally 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 significant foreign subsidiaries 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) income, 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 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 the completed sales. These credits cannot be estimated in advance. Such credits are infrequent and situation-specific. 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 consolidated statements of operations. 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 Revenues 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. 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 significant foreign subsidiaries 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. No single customer individually accounted for 10% or more of our consolidated revenue during 2019 and 2018. For the year ended December 31, 2017, there was one customer that accounted for 10% or more of the total revenue. We recognized revenue from this customer totaling $27.4 million, or 14% of 2017 total revenue for the year ended December 31, 2017. One customer accounted for 10% of our trade receivable accounts balance as of December 31, 2019 and another customer accounted for 12% of our trade receivable accounts balance as of December 31, 2018. 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, 2019 and 2018 , we have recorded $0.5 million and $0.3 million, respectively, in provisions for doubtful accounts. Inventories Inventories consist primarily of raw material, product components, assembled products, certain components used to internally construct our frac isolation assemblies and chemicals, in raw material or finished goods, used in our tracer diagnostics services. 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. 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. Impairments We evaluate our property and equipment and finite-lived intangible assets for impairment whenever changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. Should the review indicate that the carrying value is not fully recoverable, the amount of the impairment loss is determined by comparing the carrying value to the estimated fair value. We assess recoverability based on undiscounted future net cash flows. Estimating future net cash flows requires us to make judgements regarding long-term forecasts of future revenues and costs related to the assets subject to review. These forecasts are uncertain in that they require assumptions about our revenue growth, operating margins, capital expenditures, future market conditions and technological developments. If changes in these assumptions occur, our expectations regarding future net cash flows may change such that a material impairment could result. No fixed asset or finite-lived intangible impairments were recorded in 2019 or 2017 . We recorded an impairment of $73.5 million related to identifiable intangible assets, which we recorded in the fourth quarter of 2018. For additional information, s ee “Note 7. Goodwill and Intangibles”. There was no impairment related to fixed assets in 2018. An assessment for goodwill impairment is performed annually or when there is an indication an impairment may have occurred. We typically complete our annual impairment test for goodwill using an assessment date in the fourth quarter of each fiscal year. Under generally accepted accounting principles, we have the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of one or more of our reporting units is greater than its carrying amount. If, after assessing the totality of events or circumstances, we determine it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, there is no need to perform any further testing. However, if we conclude otherwise, then we are required to perform a quantitative impairment test by calculating the fair value of the reporting unit and comparing the fair value with the carrying value of the reporting unit. We also have the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to performing the quantitative goodwill impairment test. T he fair value of the reporting unit is determined using a combination of a market multiple and a discounted cash flow approach. Determining the fair value of a reporting unit requires the use of estimates, assumptions and judgement. The principal estimates and assumptions that we use include revenue growth, operating margins, capital expenditures, future market conditions, weighted average costs of capital, a terminal growth rate, the set of comparable companies utilized, and the earnings metrics and multiples utilized. We believe that the estimates and assumptions used in impairment assessments are reasonable . If the fair value of the reporting unit is less than its carrying amount, an impairment charge is recorded based on that difference. We recorded an impairment charge of $7.9 million and $154.0 million for the years ended December 31, 2019 and 2018, respectively. For additional information, s ee “Note 7. Goodwill and Intangibles”. No impairments were recorded in 2017. Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Equipment held under finance 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 finance 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 finance 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 income, net in the year of disposal. Depreciation on property and equipment, including assets held under finance 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 2-4 Leasehold improvements Lease term ( 1 - 5 ) 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. 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. 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 when it is ready for its intended use. These assets are tested for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Income Taxes We are 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 it is more likely than not that some portion or all the deferred tax assets will not be realized. As of December 31, 2019 and 2018 , our valuation allowance was $14.2 million and $1.1 million, respectively. We recognize accrued interest and penalties related to uncertain tax positions in other income, net on the statements of operations. During the years ended December 31, 2019 , 2018 and 2017 , respectively, we recognized $0.1 million, $0.1 million and $0.2 million in interest and penalties. We had $0.7 million and $0.6 million in interest and penalties accrued at December 31, 2019 and 2018 , 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, 2019 and 2018 . We believe that there are no tax positions taken or expected to be taken as of December 31, 2019 and 2018 that would significantly increase or decrease unrecognized tax benefits within the next twelve months following the balance sheet date. As of December 31, 2019 and 2018 , 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 our initial public offering (“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 U.S. Tax Cuts and Jobs Act of 2017 (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. No U.S. deferred tax assets were recognized as of December 31, 2019 and 2018, respectively, on our tax basis in excess of our book value. 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. Included in tax expense for the year ended December 31, 2019 of approximately $13.1 million was a valuation allowance against our U.S. deferred tax asset based on management’s position that we have not met the more likely than not condition of realizing the deferred tax asset based on the existence of sufficient projected U.S. taxable income of the appropriate character to recognize the tax benefit as well as the tax effect of a non-deductible goodwill impairment. We file income tax returns in the U.S., Canada and various state and foreign jurisdictions. Our U.S. income tax returns for 2015 and subsequent years remain open for examination. The Internal Revenue Service (“IRS”) commenced an examination of our U.S. income tax returns for 2017 in the second quarter of 2019. No tax adjustments are proposed. During 2018, the Canada Revenue Agency (“CRA”) commenced an examination of our transfer pricing on Canadian income tax returns for the 2012 through 2015 filings and no tax adjustments have been proposed. Share-Based Compensation We account for our stock-based compensation awards in accordance with ASC Topic 718, Compensation—Stock Compensation (“ASC 718”). To measure the fair value of share-based compensation we used the market price of our common stock for equity-classified restricted stock units (“RSUs”) and equivalent stock units, or cash-settled, liability-classified RSUs (“ESUs”) , the Black-Scholes model for options and a Monte Carlo simulation for the performance stock unit awards (“PSUs”). 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 and record forfeitures as they occur. As the ESUs will be settled in cash, the compensation cost is remeasured each reporting period at fair value based upon the closing stock price of our common stock until the awards are settled. We also have an 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”), which allows eligible employees to purchase shares of our common stock. The purchase price of the stock is 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 ESPP is also estimated using the Black-Scholes model. The ESPP was temporarily suspended for future offering periods beginning on July 1, 2019. 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 secured revolving 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 Measurements . 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 4. 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 0.0% of the net loss for the years ended December 31, 2019 and 2018 , respectively, and 4.2% of the net income for the year ended December 31, 2017 . 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 RSUs and PSUs, purchases under the ESPP 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 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 products. We incurred approximately $2.8 million, $3.8 million and $3.0 million in research and development costs for the years ended December 31, 2019 , 2018 and 2017 , respectively. These costs are recorded in selling, general and administrative (“SG&A”) expenses on the consolidated statements of operations. Recent Accounting Pronouncements Pronouncement Adopted in 2019 In February 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) , which requires lessees to recognize a right-of-use (“ROU”) asset and a lease liability for all leases with terms longer than 12 months. Under the new standard, lessees need to recognize leases on their balance sheets as lease liabilities with corresponding ROU assets. We adopted the standard effective January 1, 2019, using a modified retrospective transition method and applying certain optional practical expedients. NCS elected an optional transition method that allowed application of the new standard at the adoption date and the recognition of a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption with no adjustment to previously reported results. We also elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed the carry forward of historical lease classification as well as additional practical expedients related to land easements, short-term leases, and non-lease components. We did not elect the practical expedient related to hindsight. The standard had a material impact on our consolidated balance sheet but did not materially impact our consolidated statements of operations or consolidated statements of cash flows. Adoption of the new standard resulted in the recording of ROU assets and lease liabilities of $7.5 million on January 1, 2019. See “Note 14. Leases” for more information. Pronouncements Not Yet Effective In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which is intended to simplify various aspects related to accounting for income taxes. ASU No. 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. For public entities, this guidance is effective for fiscal years beginning after December 15, 2020 and interim periods within those fiscal years. We are currently evaluating the impact of the adoption of this guidance. 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 but do not currently expect that the adoption of this guidance will have a material impact on our consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326). This ASU introduces a new impairment model that is based on expected credit losses rather than incurred credit losses for financial instruments, including trade accounts receivable. It requires an entity to measure expected credit losses for financial assets held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. The new standard is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. In November 2019, the FASB issued ASU 2019-10, which deferred effective dates for certain ASUs. The effective date for ASU 2016-13 will remain the same for public business entities that are the Securities and Exchange Commission (the “SEC”) filers, excluding entities eligible to be smaller reporting companies (“SRC”). The effective date for all other entities, including SRCs, will begin after December 15, 2022, including interim periods within those fiscal years. NCS qualifies as a SRC. We are currently evaluating the impact of the adoption of this guidance . |
