Organization, Consolidation and Presentation of Financial Statements [Abstract]
Reclassifications	Reclassifications Certain amounts in the prior period's condensed consolidated financial statements have been reclassified to conform to the current year presentation.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers” (Topic 606). ASU No. 2014-09 will replace all current U.S. GAAP guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle is that a company 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. In March 2016, the FASB issued ASU No. 2016-08, “Revenue from Contracts with Customers - Principal versus Agent Considerations” (Topic 606), which clarifies the implementation guidance on principal versus agent considerations. During 2016, the Company established a project team to identify potential differences that would result from the application of this standard. The Company is in the process of reviewing customer contracts, identifying contractual provisions that may result in a change in the timing or the amount of revenue recognized and assessing the enhanced disclosure requirements of the new guidance. The Company will adopt the requirements of the new standard on January 1, 2018 and anticipates using the modified retrospective transition method. In February 2016, the FASB issued ASU No. 2016-02, “Leases” (Topic 842), which revises the accounting related to lessee accounting. Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset for all leases with terms greater than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The provisions of ASU 2016-02 are effective for fiscal years beginning after December 15, 2018 and should be applied through a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. Early adoption is permitted. The Company is currently evaluating the impact this accounting standard will have on the Company’s consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, “Restricted Cash” (Topic 230), which 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 and restricted cash equivalents. The provisions of ASU 2016-18 are effective for fiscal years beginning after December 15, 2017 and should be applied using a retrospective transition method. Early adoption is permitted. Other than the revised statement of cash flows presentation, the adoption of ASU 2017-07 is not expected to have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, “Business Combinations - Clarifying the Definition of a Business” (Topic 805), which clarifies the definition of a business for determining whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The new standard is effective for annual periods beginning after December 15, 2017 with early adoption permitted for transactions that occurred before the issuance date or effective date of the standard if the transactions were not reported in financial statements that have been issued or made available for issuance. The standard must be applied prospectively. The Company is currently evaluating the impact this accounting standard will have on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04 “Intangibles - Goodwill and Other - Simplifying the Test for Goodwill Impairment” (Topic 350), which simplifies subsequent goodwill measurement by eliminating Step 2 from the goodwill impairment test. Under 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. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The new standard is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2019 with early adoption permitted for annual goodwill impairment tests performed after January 1, 2017. The standard must be applied prospectively. The Company early-adopted the guidance of this accounting standard during the second quarter of fiscal 2017 in connection with its annual impairment testing to reduce the complexity and costs of evaluating goodwill for impairment. It was adopted on a prospective basis. As a result of the adoption, a single step quantitative test was performed. Refer to Note 5 for further discussion. In March 2017, the FASB issued ASU No. 2017-07 “Compensation-Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” (Topic 715), which provides guidance that requires an employer to report the service cost component separate from the other components of net benefit pension costs. The employer is required to report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside the subtotal of income from operations, if one is presented. If a separate line item is not used, the line item used in the income statement must be disclosed. The new standard is effective for annual reporting periods beginning after December 15, 2017 and interim periods within those years. Early adoption is permitted. Other than the revised statement of operations presentation, the adoption of ASU 2017-07 is not expected to have a material impact on the Company’s consolidated financial statements. All other issued and not yet effective accounting standards are not relevant to the Company.
