Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Basis of Presentation and Consolidation The accompanying interim unaudited condensed consolidated financial statements of Solaris have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These financial statements reflect all normal recurring adjustments that are necessary for fair presentation. Operating results for the three and nine months ended September 30, 2017 and 2016 are not necessarily indicative of the results that may be expected for the full year or for any interim period. The unaudited interim condensed consolidated financial statements should be read in conjunction with Solaris’ final prospectus, dated May 11, 2017, filed in connection with the IPO pursuant to Rule 424(b) under the Securities Act of 1933, as amended (the “Securities Act”), with the SEC on May 15, 2017 (the “Prospectus”). As discussed in Note 1, as a result of the Reorganization Transactions, the Company is the sole managing member for Solaris LLC and consolidates entities in which it has a controlling financial interest. The Reorganization Transactions were considered transactions between entities under common control. As a result, the financial statements for periods prior to the IPO and the Reorganization Transactions have been adjusted to combine the previously separate entities for presentation purposes. Thus, for periods prior to the completion of the offering, the accompanying condensed consolidated financial statements include the historical financial position and results of operations of Solaris LLC and its subsidiaries, Solaris Oilfield Site Services Operating, LLC, Solaris Oilfield Early Property, LLC, Solaris Oilfield Site Services Personnel, LLC, Solaris Oilfield Infrastructure Personnel, LLC and Solaris Logistics, LLC (collectively, the “Subsidiaries”) . For periods after the completion of the offering, the financial position and results of operations include those of the Company and the Subsidiaries and report non-controlling interest related to the portion of Solaris LLC Units not owned by Solaris . All material intercompany transactions and balances have been eliminated upon consolidation. Use of Estimates The preparation of condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant estimates used in the preparation of these condensed consolidated financial statements include, but are not limited to, depreciation associated with property, plant and equipment and related impairment considerations of those assets, and certain liabilities. Actual results could differ from management’s best estimates as additional information or actual results become available in the future, and those differences could be material. Cash For the purposes of the statements of cash flows, the Company considers all short-term, highly liquid, investments with an original maturity of three months or less to be cash equivalents. Cash is deposited in demand accounts in federally insured domestic institutions to minimize risk. Accounts at each institution are insured by Federal Deposit Insurance Corporation. Cash balances at times may exceed federally-insured limits. We have not incurred losses related to these deposits. Accounts Receivable Accounts receivable consists of trade receivables recorded at the invoice amount, plus accrued revenue that is earned but not yet billed, less an estimated allowance for doubtful accounts (if any). Accounts receivable are generally due within 60 days or less, or in accordance with terms agreed with customers, and are stated at amounts due from customers net of any allowance for doubtful accounts. The Company considers accounts outstanding longer than the payment terms past due. The Company determines the allowance by considering a number of factors, including the length of time trade accounts receivable are past due, previous loss history, the customer’s current ability to pay its obligation, and the condition of the general economy and the industry as a whole. Accounts receivable are written off when they are deemed uncollectible, and payments subsequently received on such receivables are credited to the allowance for doubtful accounts. As of December 31, 2016, Solaris LLC had $131 of allowance for doubtful accounts which was subsequently deemed uncollectible. The allowance for doubtful accounts of $131 and the related accounts receivable balance were fully extinguished in the first quarter of 2017. Allowance for doubtful accounts is zero as of September 30, 2017. Inventories Inventories consist of materials used in the manufacturing of the Company’s systems, which include raw materials and purchased parts. Inventory purchases are recorded initially at cost, adjusted each quarter to measure inventory at the lower of cost or net realizable value, where net realizable value approximates estimated selling prices in the ordinary course of business. Adjustments that reduce the average cost will be recognized as impairments in the condensed consolidated statements of operations. There were no impairments recorded for the three and nine months ended September 30, 2017 and 2016. Property, Plant and Equipment Property, plant and equipment are stated at cost, or fair value for assets acquired in a business combination, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful service lives of the assets as noted below: Useful Life Proppant management systems and related equipment Up to 15 years Machinery and equipment 2-10 years Furniture and fixtures 5 years Computer equipment 3 years Vehicles 5 years Buildings 15 years Systems that are in the process of being manufactured are considered property, plant and equipment. However, the systems in process do not depreciate until they are fully completed. Systems in process are a culmination of material, labor and overhead. Expenditures for maintenance and repairs are charged against income (loss) as incurred. Betterments that increase the value or materially extend the life of the related assets are capitalized. Upon sale or disposition of property and equipment, the cost and related accumulated depreciation and amortization are removed from the condensed consolidated financial statements and any resulting gain or loss is recognized in the condensed consolidated statements of operations. The Company, on occasion, has had vehicles that are pledged against the respective notes payables for those vehicles. As of September 30, 2017, there were no vehicles pledged against notes payable. As of December 31, 2016, the cost of vehicles pledged was $859. Definite-lived Intangible Assets As of September 30, 2017 and December 31, 2016, the Company reported $67 and $36, respectively, of costs that were capitalized as definite-lived intangible assets. These intangible assets are related to patents that were filed for its systems. Amortization on these assets is calculated on the straight-line method over the estimated useful lives of the assets, which is fifteen years based on estimates the Company believes are reasonable. Goodwill Goodwill represents the excess of the purchase price of a business over the estimated fair value of the identifiable assets acquired and liabilities assumed. The Company evaluates goodwill for impairment annually, as of October 31, or more often as facts and circumstances warrant. Factors such as unexpected adverse economic conditions, competition and market changes may require more frequent assessments. There was no impairment for the three and nine months ended September 30, 2017 and 2016. Before employing detailed impairment testing methodologies, the Company may first evaluate the likelihood of impairment by considering qualitative factors relevant to the business, such as macroeconomic, industry, market or any other factors that have a significant bearing on fair value. If the Company first utilizes a qualitative approach and determines that it is more likely than not that goodwill is impaired, detailed testing methodologies are then applied. Otherwise, the Company concludes that no impairment has occurred. The Company may also choose to bypass a qualitative approach and opt instead to employ detailed testing methodologies, regardless of a possible more likely than not outcome. The first step in the goodwill impairment test is to compare the fair value of the business to the carrying amount of net assets, including goodwill, of the respective reporting unit. If the carrying amount of the business exceeds its fair value, step two in the goodwill impairment test requires goodwill to be written down to its implied fair value through a charge to operating expense based on a hypothetical purchase price allocation. Impairment of Long-Lived Assets and Definite-lived Intangible Assets Long-lived assets, such as property, plant, equipment and definite-lived intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable, such as insufficient cash flows or plans to dispose of or sell long-lived assets before the end of their previously estimated useful lives. If the carrying amount is not recoverable, the Company recognizes an impairment loss equal to the amount by which the carrying amount exceeds fair value. The Company estimates fair value based on projected future discounted cash flows. Fair value calculations for long-lived assets and intangible assets contain uncertainties because it requires the Company to apply judgment and estimates concerning future cash flows, strategic plans, useful lives and market performance. The Company also applies judgment in the selection of a discount rate that reflects the risk inherent in the current business model. There was no impairment for the three and nine months ended September 30, 2017 and 2016. Revenue Recognition The Company currently generates revenue primarily through the rental of its systems and related services, including transportation of its systems and field supervision and support. The system rentals and provision of related services are performed under a variety of contract structures, primarily master service agreements as supplemented by individual work orders detailing statements of work, pricing agreements and specific quotes. The master service agreements generally establish terms and conditions for the provision of the Company’s systems and service on a well site, indemnification, damages, confidentiality, intellectual property protection and payment terms and provisions. The services are generally priced based on prevailing market conditions at the time the services are provided, giving consideration to the specific requirements and activity levels of the customer. All revenue is recognized when persuasive evidence of an arrangement exists, the service is complete, the amount is determinable and collectability is reasonably assured. Revenue is recognized as services are performed. Taxes collected from customers and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from revenues in the condensed consolidated statements of operations. Stock-based Compensation The Company accounts for its stock-based compensation including grants of restricted stock and options in the condensed consolidated statements of operations based on their estimated fair values. The Company recognizes expense on a straight-line basis over the vesting period of the respective grant. Solaris LLC previously sponsored a stock-based management compensation program called the 2015 Membership Unit Option Plan (the “Plan”). Solaris LLC accounted for the units under the Plan as compensation cost measured at the fair value of the award on the date of grant using the Black-Scholes option-pricing model. In connection with the Offering, the options granted under the Plan were modified by a conversion into options under the Solaris Long-Term Incentive Plan (the “LTIP”). Refer also to Note 9. Research and Development The Company expenses research and development costs as incurred, which is included in selling, general and administrative expenses in the condensed consolidated statements of operations. For the three months ended September 30, 2017 and 2016, research and development costs were $1 and $42, respectively. For the nine months ended September 30, 2017 and 2016, research and development costs were $197 and $468, respectively. Financial Instruments The carrying value of the Company’s financial instruments, consisting of cash, accounts receivable, notes receivable, accounts payable and accrued expenses, approximates their fair value due to the short maturity of such instruments. Financial instruments also consist of the Revolving Facility and Advance Loan Facility (each as defined below), for which fair value approximates carrying value as the debt bears interest at a variable rate which is reflective of current rates otherwise available to the Company. Unless otherwise noted, it is management’s opinion that the Company is not exposed to significant interest, currency or credit risks arising from these financial instruments. Fair Value Measurements The Company’s financial assets and liabilities are to be measured using inputs from the three levels of the fair value hierarchy, of which the first two are considered observable and the last unobservable, which are as follows: · Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date; · Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active or other inputs corroborated by observable market data for substantially the full term of the assets or liabilities; and · Level 3—Unobservable inputs that reflect the Company’s assumptions that market participants would use in pricing assets or liabilities based on the best information available. Income Taxes Solaris is a corporation and as a result, is subject to U.S. federal, state and local income taxes. We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events included in the condensed consolidated financial statements. Under this method, we determine deferred tax assets and liabilities on the basis of the differences between the book value and tax bases of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period in which the enactment date occurs. We recognize deferred tax assets to the extent we believe these assets are more-likely-than-not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent results of operations. We record uncertain tax positions on the basis of a two-step process in which (1) we determine whether it is more-likely-than-not the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions meeting the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority. Interest and penalties related to income taxes are included in the benefit (provision) for income taxes in our condensed consolidated statement of operations. We have not incurred any significant interest or penalties related to income taxes in any of the periods presented. Solaris LLC is treated as a partnership for U.S. federal income tax purposes and therefore does not pay U.S. federal income tax on its taxable income. Instead, the Solaris LLC members are liable for U.S. federal income tax on their respective shares of the Company’s taxable income reported on the members’ U.S. federal income tax returns. Our revenues are derived through transactions in several states, which may be subject to state and local taxes. Accordingly, we have recorded a liability for state and local taxes that management believes is adequate for activities as of September 30, 2017 and as of December 31, 2016. We are subject to a franchise tax imposed by the State of Texas. The franchise tax rate is 1%, calculated on taxable margin. Taxable margin is defined as total revenue less deductions for cost of goods sold or compensation and benefits in which the total calculated taxable margin cannot exceed 70% of total revenue. Total expenses related to the Texas franchise tax were approximately $30 and $13 for the three months ended September 30, 2017 and 2016, respectively. Total expenses related to the Texas franchise tax were approximately $75 and $26 for the nine months ended September 30, 2017 and 2016, respectively. Payable to Related Parties Pursuant to the Tax Receivable Agreement In connection with the Offering, the Company entered into a Tax Receivable Agreement (the “Tax Receivable Agreement”) with the Original Investors and permitted transferees (each such person, a “TRA Holder”) on May 17, 2017. This agreement generally provides for the payment by Solaris to each TRA Holder of 85% of the net cash savings, if any, in U.S. federal, state and local income tax or franchise tax that Solaris actually realizes (computed using simplifying assumptions to address the impact of state and local taxes or is deemed to realize in certain circumstances) as a result of (i) certain increases in tax basis that occur as a result of Solaris’ acquisition (or deemed acquisition for U.S. federal income tax purposes) of all or a portion of such TRA Holder’s Solaris LLC Units in connection with the IPO or pursuant to the exercise of the Redemption Right or the Call Right (each as defined in Solaris LLC’s amended and restated limited liability company agreement) and (ii) imputed interest deemed to be paid by Solaris as a result of, and additional tax basis arising from, any payments Solaris makes under the Tax Receivable Agreement. Solaris will retain the benefit of the remaining 15% of these cash savings. Environmental Matters The Company is subject to various federal, state and local laws and regulations relating to the protection of the environment. Management has established procedures for the ongoing evaluation of the Company’s operations, to identify potential environmental exposures and to comply with regulatory policies and procedures. Environmental expenditures that relate to current operations are expensed or capitalized as appropriate. Expenditures that relate to an existing condition caused by past operations and do not contribute to current or future revenue generation are expensed as incurred. Liabilities are recorded when environmental costs are probable, and the costs can be reasonably estimated. The Company maintains insurance which may cover in whole or in part certain environmental expenditures. As of September 30, 2017 and December 31, 2016, there were no environmental matters deemed probable. Segment Information Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker, or decision-making group, in making decisions on how to allocate resources and assess performance. The Company’s chief operating decision maker is the Chief Executive Officer. The Company and the Chief Executive Officer view the Company’s operations and manage its business as one operating segment. All long-lived assets of the Company reside in the United States. Recent Accounting Pronouncements In May 2017, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2017 09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting (“ASU 2017-09”). ASU 2017-09 clarifies when to account for a change to the terms or conditions of a share-based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. ASU 2017-09 should be applied on a prospective basis and is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted in any interim period for public business entities or reporting periods for which financial statements have not yet been issued. The Company is currently evaluating the impact of adopting this guidance on its consolidated financial statements. In February 2017, the FASB issued ASU No. 2017‑05, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610‑20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets ("ASU 2017‑05"). ASU 2017‑05 clarifies the scope of Subtopic 610‑20 and adds guidance for partial sales of nonfinancial assets. Subtopic 610‑20 was issued in May 2014 as part of ASU No. 2014‑09, Revenue from Contracts with Customers (Topic 606) and provides guidance for recognizing gains and losses from the transfer of nonfinancial assets in contracts with noncustomers. The amendments in ASU 2017‑05 clarify that a financial asset is within the scope of Subtopic 610‑20 if it meets the definition of an in substance nonfinancial asset. The amendments also clarify that nonfinancial assets within the scope of Subtopic 610‑20 may include nonfinancial assets transferred within a legal entity to a counterparty. The amendments in ASU 2017‑05 are effective at the same time as the amendments in ASU 2014‑09, which are effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Early adoption is permitted for interim or annual reporting periods beginning after December 15, 2016. An entity may elect to apply the amendments in ASU 2017‑05 either retrospectively to each period presented in the financial statements in accordance with the guidance on accounting changes (retrospective approach) or retrospectively with a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption (modified retrospective approach). The Company is currently evaluating the impact of adopting this guidance on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017‑04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017‑04”). ASU 2017‑04 simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. 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 unity with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. ASU 2017‑04 should be applied on a prospective basis and is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact of adopting this guidance on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”). ASU 2017-01 clarifies the definition of a business for determining whether transactions should be accounted for as acquisitions or disposals of assets or businesses. ASU 2017-01 provides a screen for an entity to use to determine when a set of assets and activities is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the asset is not a business. If the screen is not met, ASU 2017-01 requires that to be considered a business, a set of assets and activities must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output. ASU 2017-01 also removes the evaluation of whether a market participant could replace missing elements. ASU 2017-01 09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The Company adopted ASU 2016 09 in the third quarter of 2017 which did not have a material impact on the condensed consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash ("ASU 2016-18"). ASU 2016-18 is intended to add and clarify guidance on the classification and presentation of restricted cash on the statement of cash flows. ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The Company is in the initial stages of evaluating the potential impact this new standard may have on the consolidated financial statements. In August 2016, the FASB issued ASU 2016‑15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments ("ASU 2016-15"), seeking to eliminate diversity in practice related to how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments in ASU 2016‑15 address eight specific cash flow issues and apply to all entities, including both business entities and not-for-profit entities that are required to present a statement of cash flows under FASB ASC 230, Statement of Cash Flows. The amendments in ASU 2016‑15 are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The new standard will be effective during the first quarter ending March 31, 2018. The Company is in the initial stages of evaluating the potential impact this new standard may have on the consolidated financial statements. In March 2016, the FASB issued ASU 2016‑09, Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09"). ASU 2016‑09 simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016‑09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The Company adopted ASU 2016‑09 in the first quarter of 2017 which did not have a material impact on the condensed consolidated financial statements. ASU 2016-09 requires prospective recognition of excess tax benefits resulting from stock-based compensation vesting and exercises to be recognized as a reduction of income taxes and reflected in operating cash flows. Previously, these amounts would have been recognized in additional paid in capital and presented as a financing activity on the statement of cash flows. No net excess tax benefits were recognized as a reduction of income taxes for the three or nine months ended September 30, 2017 and 2016. The Company has elected to prospectively account for forfeitures as they occur per ASU 2016-09, contrary to previously estimating the expected forfeitures. ASU 2016-09 requires that employee taxes paid when an employer withholds shares for tax-withholding purposes to be reported as financing activities in the statement of cash flows. Previously, these cash flows would have been included in operating activities. The Company has elected to adopt this prospectively, as permitted by ASU 2016-09. This change resulted in no impact on the condensed consolidated statement of cash flows for the nine months ended September 30, 2017 and 2016. In February 2016, the FASB issued ASU No. 2016‑02, Leases (Topic 842) , as part of a joint project with the International Accounting Standards Board to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. To satisfy the foregoing objective, the FASB is creating Topic 842, Leases, which supersedes Topic 840. Under the new guidance, a lessee will be required to recognize assets and liabilities for capital and operating leases with lease terms of more than 12 months. Additionally, this ASU will require disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases, including qualitative and quantitative requirements. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. The new standard will be effective during the first quarter ending March 31, 2019. The Company is in the initial stages of evaluating the potential impact this new standard may have on the consolidated financial statements. In July 2015, the FASB issued ASU No. 2015‑11, Inventory (Topic 330): Simplifying the Measurement of Inventory (“ASU 2015-11”). This ASU requires entities measuring inventories under the first-in, first-out or average cost methods to measure inventory at the lower of cost or net realizable value, where net realizable value is “estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.” Inventory was previously required to be measured at the lower of cost or market, where the measurement of market value had several potential outcomes. The provisions of this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The Company adopted ASU 2015‑11 in the first quarter of 2017 which did not have a material impact on the condensed consolidated financial statements. In August 2014, the FASB issued ASU No. 2014‑15, Presentation of Financial Statements-Going Concern (Subtopic 205‑40)-Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”). ASU 2014‑15 provides guidance to U.S. GAAP about management’s responsibility to evaluate whether there is a substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Specifically, ASU 2014‑15 (1) defines the term substantial doubt, (2) requires an evaluation of every reporting period including interim periods, (3) provides principles for considering the mitigating effect of management’s plan, (4) requires certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) requires an express statement and other disclosures when substantial doubt is not alleviated, and (6) requires an assessment for a period of one year after the date that th |
