Organization, Consolidation and Presentation of Financial Statements [Abstract]
Goodwill	Goodwill Goodwill is recorded when the cost of acquired businesses exceeds the fair value of the identifiable net assets acquired. Goodwill has an indefinite useful life and is not amortized, but is assessed for impairment annually or when events or changes in circumstances indicate that a potential impairment exists.
Other Intangible Assets	Other Intangible Assets Intangible assets with finite useful lives are amortized over their respective estimated useful lives to their estimated residual values.
Recent Accounting Pronouncements	Recent Accounting Pronouncements We consider the applicability and impact of all accounting standard updates (“ASUs”). ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position or results of operations. In May 2014, the Financial Accounting Standards Board (the “FASB”) issued accounting guidance on revenue recognition replacing the existing accounting standard and industry-specific guidance for revenue recognition with a five-step model for recognizing and measuring revenue from contracts with customers. The underlying principle of the new standard is to recognize revenue to depict the transfer of goods or services to customers at the amount expected to be collected. This new standard is effective for annual reporting periods beginning after December 15, 2017. We adopted the standard as of April 1, 2018 using the modified retrospective method applied to open contracts and only to the version of the contracts in effect as of April 1, 2018. Prior period amounts have not been adjusted and continue to be reflected in accordance with our historical accounting policy. There was no impact on our condensed consolidated financial statements and no cumulative effect adjustment was recognized. For further details, see Note 2. In February 2016, the FASB issued accounting guidance which amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. This accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, with early adoption permitted. Additionally, this accounting guidance requires a modified retrospective transition approach for all leases existing at, or entered into after the date of initial application, with an option to use certain transition relief. We have not yet adopted this standard and are currently evaluating the effect this standard will have on our financial statements. In October 2016, the FASB issued accounting guidance related to current and deferred income taxes for intra-entity transfer of assets other than inventory. This accounting guidance requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs and eliminates the exception for an intra-entity transfer of an asset other than inventory. This accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and early adoption is permitted. We adopted this accounting guidance effective April 1, 2018 using the modified retrospective method, through a cumulative-effect adjustment directly to retained earnings. Upon adoption, we increased deferred tax liabilities by approximately $1.7 million and recognized an offsetting decrease to retained earnings. In January 2017, the FASB issued accounting guidance which clarifies the definition of a business with the objective of adding guidance to assist in evaluating whether transactions should be accounted for as acquisitions of assets or businesses. The amendment provides criteria for determining when a transaction involves the acquisition of a business. If substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, then the transaction does not involve the acquisition of a business. If the criteria are not met, then the amendment requires that to be considered a business, the operation must include at a minimum an input and a substantive process that together significantly contribute to the ability to create an output. The guidance may reduce the number of transactions accounted for as business acquisitions. This accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and early adoption is permitted. The amendments should be applied prospectively, and no disclosures are required at the effective date. We adopted this accounting guidance effective April 1, 2018. This accounting guidance has had no impact on our financial statements since adoption as we have not entered into any transactions during this period. In March 2017, the FASB issued accounting guidance related to the presentation of net periodic pension cost and net periodic post-retirement benefit cost. The accounting guidance requires employers to disaggregate the service cost component from the other components of net benefit cost and disclose the amount of net benefit cost that is included in the statement of operations or capitalized in assets, by line item. The accounting guidance requires employers to report the service cost component in the same line item(s) as other compensation costs and to report other pension-related costs (which include interest costs, amortization of pension-related costs from prior periods, and the gains or losses on plan assets) separately and exclude them from the subtotal of operating income. The accounting guidance also allows only the service cost component to be eligible for capitalization when applicable. This accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and early adoption is permitted as of the first interim period of an annual period for which interim or annual financial statements have not been issued. The accounting guidance requires application on a retrospective basis for the presentation of the service cost component and the other components of net periodic pension cost and net periodic post-retirement benefit cost in the statement of operations and on a prospective basis for the capitalization of the service cost component of net periodic pension cost and net periodic post-retirement benefit in assets. We adopted this accounting guidance effective April 1, 2018 and our statement of operations was retrospectively adjusted by $0.1 million with an increase in direct cost and a corresponding credit in other income (expense), net for the three months ended June 30, 2017. In May 2017, the FASB issued accounting guidance on determining which changes to the terms or conditions of share-based payment awards require an entity to apply modification accounting. This pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted, and is applied prospectively to changes in terms or conditions of awards occurring on or after the adoption date. We have adopted this accounting guidance effective April 1, 2018 with no impact on our financial statements as there were no changes to the terms or conditions of share-based payment awards. In February 2018, the FASB issued new accounting guidance on income statement reporting of comprehensive income, specifically pertaining to reclassification of certain tax effects from accumulated other comprehensive income. This pronouncement is effective for fiscal years, and for interim periods within those years, beginning after December 15, 2018, with early adoption permitted, and is applied prospectively to changes in terms or conditions of awards occurring on or after the adoption date. We have not yet adopted this accounting guidance and are currently evaluating the effect this accounting guidance will have on our financial statements.
