Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. The Company evaluates its estimates based on historical experience, current conditions and various other assumptions that it believes are reasonable under the circumstances. Estimates and assumptions are reviewed on an on-going basis and the effects of revisions are reflected in the period in which they are deemed to be necessary. Actual results could differ significantly from those estimates.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Presentation of Net Periodic Pension Cost In March 2017, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2017-07, “Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost,” which requires employers that offer or maintain defined benefit plans to disaggregate the service component from the other components of net benefit cost and provides guidance on the presentation of the service component and the other components of net benefit cost in the statement of operations. The new standard is effective for public companies for annual periods beginning after December 15, 2017. The Company expects to adopt the new standard in the first quarter of 2018 and expects to report its net periodic pension cost related to its frozen U.K. pension plan in Other income/(expense) in the consolidated statement of operations upon adoption. Goodwill Impairment In January 2017, the FASB issued ASU 2017-04, “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” which simplifies the accounting for goodwill impairment. The amendment in ASU 2017-04 removes Step-two of the goodwill impairment test, which requires a hypothetical purchase price allocation. ASU 2017-04 will become effective prospectively for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. The Company is currently evaluating the impact of the new standard on our consolidated financial statements. Statement of Cash Flows Classification of Certain Cash Receipts and Cash Payments In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments.” The standard further clarifies the classification in the cash flow statement of the following items: (i) debt prepayment or debt extinguishment costs; (ii) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; (iii) contingent consideration payments made after a business combination; (iv) proceeds from the settlement of insurance claims; (v) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; (vi) distributions received from equity method investees; (vii) beneficial interests in securitization transactions; and (viii) separately identifiable cash flows and application of the predominance principle. ASU 2016-15 will become effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. ASU 2016-15 should be applied using a retrospective transition method for each period presented. The Company adopted ASU 2016-15 during the first quarter of 2017. The adoption of ASU 2016-15 resulted in ($2.4) million of payments of contingent considerations being reported as cash used in financing activities on the Company’s consolidated statements of cash flows for the three months ended March 31, 2017. Leases In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” which provides comprehensive lease accounting guidance. The standard requires entities to recognize lease assets and liabilities on the balance sheet and to disclose key information about leasing arrangements. ASU 2016-02 will become effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact of the new standard on our consolidated financial statements. Revenue from Contracts with Customers In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” which provides guidance for revenue recognition. ASU 2014-09 supersedes the revenue recognition requirements in ASC 605, “Revenue Recognition” (Topic 605), and requires entities to recognize revenue in a way that depicts the transfer of goods or services to customers at an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 will be effective for annual and interim reporting periods beginning after December 15, 2016. Early adoption is not permitted. Upon adoption, an entity may apply the new guidance either retrospectively to each prior reporting period presented or retrospectively only to customer contracts not yet completed as of the date of adoption with the cumulative effect of initially applying the standard recognized in beginning retained earnings at the date of the initial application. In August 2015, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers – Deferral of the Effective Date,” which defers the effective date of ASU 2014-09 by one year, with the option of early adoption as of the original effective date. The amendment in ASU 2015-14 will result in ASU 2014-09 being effective for annual and interim reporting periods beginning after December 15, 2017. The Company has identified various revenue streams that could be impacted by Topic 606 and has started to review individual customer contracts related to these various revenue streams to determine if any material differences exist between Topic 605 and Topic 606. The Company will adopt Topic 606 in the first quarter of 2018 and has preliminarily concluded that it will use the modified retrospective method upon adoption.
