SIGNIFICANT ACCOUNTING POLICIES
SIGNIFICANT ACCOUNTING POLICIES	NOTE 2—SIGNIFICANT ACCOUNTING POLICIES Significant accounting policies: Our significant accounting policies are disclosed in Note 2 of the consolidated financial statements for the years ended December 31, 2016 and 2015 included in the Final Prospectus. There have been no changes in such policies or the application of such policies during the quarter ended September 30, 2017. 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. On an ongoing basis, the Company evaluates its estimates, including those related to recoverability of long‑lived assets and intangibles, useful lives used in depreciation and amortization, uncollectible accounts receivable, income taxes, self‑insurance liabilities, share‑based compensation and contingent liabilities. The Company bases its estimates on historical and other pertinent information that are believed to be reasonable under the circumstances. The accounting estimates used in the preparation of the consolidated financial statements may change as new events occur, as more experience is acquired, as additional information is obtained and as the Company’s operating environment changes. Emerging Growth Company status: Under the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), we are an “emerging growth company,” or an “EGC,” which allows us to have an extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act. We intend to take advantage of all of the reduced reporting requirements and exemptions, including the longer phase‑in periods for the adoption of new or revised financial accounting standards under Section 107 of the JOBS Act until we are no longer an emerging growth company. Our election to use the phase‑in periods permitted by this election may make it difficult to compare our financial statements to those of non‑emerging growth companies and other emerging growth companies that have opted out of the longer phase‑in periods under Section 107 of the JOBS Act and who will comply with new or revised financial accounting standards. If we were to subsequently elect instead to comply immediately with these public company effective dates, such election would be irrevocable pursuant to Section 107 of the JOBS Act. Recent accounting pronouncements: In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606), outlining a comprehensive new revenue recognition standard that will supersede ASC 605, Revenue Recognition. The new accounting guidance creates a framework under which an entity will allocate the transaction price to separate performance obligations and recognize revenue when each performance obligation is satisfied. Under the new standard, entities will be required to use judgment and make estimates, including identifying performance obligations in a contract, estimating the amount of variable consideration to include in the transaction price, allocating the transaction price to each separate performance obligation, and determining when an entity satisfies its performance obligations. The standard allows for either “full retrospective” adoption, meaning that the standard is applied to all of the periods presented with a cumulative catch‑up as of the earliest period presented, or “modified retrospective” adoption, meaning the standard is applied only to the most current period presented in the financial statements with a cumulative catch‑up as of the current period. In August 2015, the FASB decided to defer the original effective date by one year. As long as the Company is an EGC and able to utilize the extended transition period for new accounting pronouncements, this guidance will be effective for annual reporting periods beginning after December 15, 2018, and interim reporting periods within annual reporting periods beginning after December 15, 2019. The Company is still evaluating the impact that the new accounting guidance will have on its consolidated financial statements and related disclosures and has not yet determined the method by which it will adopt the standard. In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes, which amends existing guidance on income taxes to require the classification of all deferred tax assets and liabilities as noncurrent on the balance sheet. As an EGC utilizing the extended transition period for new accounting pronouncements, this pronouncement is effective for annual reporting periods beginning after December 15, 2017, and interim periods within annual periods beginning after December 15, 2018, and may be applied either prospectively or retrospectively. The Company prospectively adopted this guidance during the nine months ended September 30, 2017. Prior periods were not retrospectively adjusted. As the Company’s deferred tax assets and liabilities are all noncurrent, the adoption did not result in a change to the consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU 2016-02, Leases, which introduces a lessee model that brings most leases on the balance sheet. The new standard also aligns many of the underlying principles of the new lessor model with those in the current accounting guidance as well as the FASB’s new revenue recognition standard. However, the ASU eliminates the use of bright‑line tests in determining lease classification as required in the current guidance. The ASU also requires additional qualitative disclosures along with specific quantitative disclosures to better enable users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. As an EGC utilizing the extended transition period for new accounting pronouncements, this pronouncement is effective for annual reporting periods beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020, using a modified retrospective approach. Early adoption is permitted. The Company is still evaluating the impact that the new accounting guidance will have on its consolidated financial statements and related disclosures. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, that provides a new requirement to record all of the tax effects related to share‑based payments at settlement (or expiration) through the income statement. As an EGC utilizing the extended transition period for new accounting pronouncements, this pronouncement is effective for annual reporting periods beginning after December 15, 2017, and interim periods within fiscal years beginning after December 15, 2018. The Company is still evaluating the impact that the new accounting guidance will have on its consolidated financial statements and related disclosures. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments, which addresses the classification and presentation of eight specific cash flow issues that currently result in diverse practices. The amendments provide guidance in the presentation and classification of certain cash receipts and cash payments in the statement of cash flows including debt prepayment or debt extinguishment costs, settlement of zero‑coupon debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate‑owned life insurance policies, and distributions received from equity method investees. As an EGC utilizing the extended transition period for new accounting pronouncements, this pronouncement is effective for annual reporting periods beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. The amendments in this ASU should be applied using a retrospective approach. The Company is still evaluating the impact that the new accounting guidance will have on its consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU 2017-01, Clarifying 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. As an EGC utilizing the extended transition period for new accounting pronouncements, this pronouncement is effective for annual reporting periods beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. The amendments in this ASU should be applied prospectively. The Company is still evaluating the impact that the new accounting guidance will have on its consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment. This pronouncement removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. This pronouncement is effective for annual reporting periods beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2019. The amendments in this ASU should be applied prospectively. The Company is still evaluating the impact that the new accounting guidance will have on its consolidated financial statements and related disclosures. In May 2017, the FASB issued ASU 2017-09, Scope of Modification Accounting. This pronouncement provides guidance about which changes to the terms and conditions of a share-based payment award require an entity to apply modification accounting in ASC 718. This pronouncement is effective for annual reporting periods beginning after December 15, 2017, and interim periods within fiscal years beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period. The pronouncement should be applied prospectively to an award modified on or after the adoption date. The Company is still evaluating the impact that the new accounting guidance will have on its consolidated financial statements and related disclosures.
