Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Use of Estimates - The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts disclosed in the financial statements and accompanying notes. Estimates, by their nature, are based on judgment and available information. Actual results could differ materially from those estimates. Significant estimates inherent in the preparation of the accompanying consolidated financial statements include the assumptions used in the determination of the allowance for doubtful accounts receivable, impairment assessment of goodwill, determination of the recoverability of long-lived assets, assessment of legal contingencies and calculation of income taxes. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09 (Topic 606) Revenue from Contracts with Customers (ASU 2014-09). ASU 2014-09 supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific revenue guidance in addition to some cost guidance. ASU 2014-09 establishes a five-step model under the core principle that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company may apply this guidance using either a full retrospective approach, subject to certain practical expedients, or a modified retrospective approach with a cumulative effect adjustment as of the date of initial application. On July 9, 2015, the FASB approved a one-year deferral of the effective date that allows the Company to defer the effective date to January 1, 2018. In 2016, the FASB issued two amendments that are effective as of the effective date selected for the original standard. The Company has begun to evaluate the impact that adoption of this guidance will have on its consolidated financial statements but has not completed the evaluation and implementation process. The Company has not yet selected a transition method but has determined that it will utilize the deferred effective date of January 1, 2018 to adopt the standard. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which supersedes ASC 840, Leases (ASU 2016-02). ASU 2016-02 requires lessees to recognize a right-of-use asset and lease liability for all leases with terms of more than 12 months. Lessees are permitted to make an accounting policy election to not recognize the asset and liability for leases with a term of twelve months or less. ASU 2016-02 does not significantly change the lessees’ recognition, measurement and presentation of expenses and cash flows from the previous accounting standard. Lessors’ accounting is largely unchanged from the previous accounting standard. In addition, ASU 2016-02 expands the disclosure requirements of lease arrangements. Lessees and lessors will use a modified retrospective transition approach. The guidance is effective for the Company beginning January 1, 2019. Early adoption is permitted. The Company has not determined the impact that adoption of this guidance will have on its consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13). ASU 2016-13 changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. The standard is effective for interim and annual reporting periods beginning after December 15, 2019. Early adoption is permitted for interim and annual reporting periods beginning after December 15, 2018. The Company has not determined the impact that adoption of this guidance will have on its consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 320): Classification of Certain Cash Receipts and Cash Payments (ASU 2016-15). ASU 2016-15 clarifies how certain cash receipts and payments should be presented in the statement of cash flows. The standard is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted for interim and annual reporting periods with retrospective application for all periods presented. The Company has not determined the impact that adoption of this guidance will have on its consolidated financial statements. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory, which requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, and should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings at the beginning period of adoption. Early adoption is permitted in the first interim period of an annual reporting period for which financial statements have not been issued. The Company does not expect that adoption of this guidance will have a material impact 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. This ASU clarifies the definition of a business and provides a framework to evaluate when an input and a substantive process are present in an acquisition to be considered a business. The standard is effective for annual periods beginning after December 15, 2017. The Company does not expect that adoption of this guidance will have a material impact on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350), which will simplify the goodwill impairment calculation. The standard eliminates the second step of the goodwill impairment test which requires an entity to determine the implied fair value of the reporting unit’s goodwill. Instead, an entity should recognize an impairment loss if the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit, with the impairment loss not to exceed the amount of goodwill allocated to the reporting unit. The standard is effective for annual and interim goodwill impairment tests conducted in fiscal years beginning after December 15, 2019, with early adoption permitted. The Company adopted the provision of ASU 2017-04 prospectively during the second quarter of 2017. In May 2017, the FASB issued ASU No. 2017-09, Compensation-Stock Compensation (Topic 718) Scope of Modification Accounting (ASU 2017-09). ASU 2017-09 clarifies which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. The standard is effective for interim and annual reporting periods beginning after December 15, 2017, with early adoption permitted. The Company has not determined the impact that adoption of this guidance will have on its consolidated financial statements.
