Organization, Consolidation and Presentation of Financial Statements [Abstract]
New Accounting Pronouncements	Recently Adopted Accounting Guidance In May 2014, the Financial Accounting Standard Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09 (Topic 606) “Revenue from Contracts with Customers.” (“ASC 606”). ASC 606 supersedes the revenue recognition requirements in Accounting Standards Codification 605 “Revenue Recognition” (“ASC 605”), and requires entities to recognize revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The Company adopted ASC 606 as of January 1, 2018 using the modified retrospective transition method. See “Note 2 - Revenues” for further details. In March 2017, the FASB issued ASU No. 2017-07, “Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” (“ASU 2017-07”), which provides guidance to improve the reporting of net periodic benefit cost in the income statement and on the components eligible for capitalization in assets. Under the new guidance, employers will present the service cost component of net periodic benefit cost in the same income statement line item(s) as other employee compensation costs arising from services rendered during the period. Only the service cost component will be eligible for capitalization in assets. Additionally, under this guidance, employers will present the other non-service components of the net periodic benefit cost separately from the line item(s) that includes the service cost and outside of any subtotal of operating income, if one is presented. Employers will apply the guidance on the presentation of the components of net periodic benefit cost in the income statement retrospectively. The guidance limiting the capitalization of net periodic benefit cost in assets to the service cost component will be applied prospectively. The guidance includes a practical expedient allowing entities to estimate amounts for comparative periods using the information previously disclosed in their pension and other postretirement benefit plan note to the financial statements. The amendments in this ASU are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The Company adopted ASU 2017-07 effective January 1, 2018 and applied the new guidance retrospectively in the Condensed Consolidated Statements of Operations. Income and expense amounts related to non-service components of net periodic benefit cost, historically recorded within Operating expenses and General and administrative expenses, have been recorded within Other income (expense). For the three and nine months ended September 30, 2018, the Company recorded income of $278 and $833, respectively, related to non-service components of net periodic benefit cost. For the three and nine months ended September 30, 2017, the Company recorded expense of $103 and $305, respectively, related to non-service components of net periodic benefit cost. In May 2017, the FASB issued ASU No. 2017-09, “Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting” (“ASU 2017-09”), which provides guidance to increase clarity and reduce both diversity in practice and cost and complexity when applying the existing accounting guidance on changes to the terms or conditions of a share-based payment award. The amendments in ASU 2017-09 require an entity to account for the effects of a modification unless all the following are met: (i) the fair value of the modified award is the same as the fair value of the original award immediately before the original award is modified; (ii) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified; and (iii) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The guidance in ASU 2017-09 should be applied prospectively. The amendments in this ASU are effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The Company’s adoption of this guidance did not materially impact its condensed consolidated financial statements. Recent Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”), to increase the transparency and comparability about leases among entities. Additional ASUs have been issued subsequent to ASU 2016-02 to provide supplementary clarification and implementation guidance for leases related to, among other things, the application of certain practical expedients, the rate implicit in the lease, lessee reassessment of lease classification, lessor reassessment of lease term and purchase options, variable payments that depend on an index or rate and certain transition adjustments (collectively, the Company refers to ASU 2016-02 and these additional ASUs as the “Updated Lease Guidance”). The Updated Lease Guidance requires lessees to recognize a lease liability and a corresponding lease asset for virtually all lease contracts. It also requires additional disclosures about leasing arrangements. The Updated Lease Guidance is effective for interim and annual periods beginning after December 15, 2018, and allows a modified retrospective approach to adoption. While early adoption is permitted, the Company will not early adopt the Updated Lease Guidance. The Company has established a working group to study the implementation of the Updated Lease Guidance and has instituted a task plan designed to meet the requirements and implementation deadline. The Company has also evaluated and purchased a lease software system, completed software design and configuration of the system, and substantially completed testing the implementation of the selected system. The working group continues to evaluate the impact of the Updated Lease Guidance on the Company’s consolidated financial statements and related disclosures and has designed and begun implementing business processes and controls to address the new guidance. While the assessment of this standard is ongoing, the Company has identified that the most significant impacts of the Updated Lease Guidance will be to bring nearly all leases, with the exception of certain short-term leases, on its balance sheet reflected as right of use assets and lease obligation liabilities as well as accelerating recognition of the interest expense component of financing leases. The new standard will also require additional disclosures for financing and operating leases. The Updated Lease Guidance allows for certain practical expedients, certain of which the Company has elected to adopt including, among others, the expedient to carry forward the classification of leases under current lease guidance once the Updated Lease Guidance becomes effective, the expedient to not include short-term leases on its balance sheet and to avail itself of the additional transition method whereby it will apply the Updated Lease Guidance on the effective date and recognize a cumulative-effect adjustment to opening retained earnings. In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities” (“ASU 2017-12”). The amendments in ASU 2017-12 more closely align the results of cash flow and fair value hedge accounting with risk management activities in the consolidated financial statements. The amendments expand the ability to hedge nonfinancial and financial risk components, reduce complexity in fair value hedges of interest rate risk, eliminate the requirement to separately measure and report hedge ineffectiveness, and eases certain hedge effectiveness assessment requirements. The guidance in ASU 2017-12 should be applied using a modified retrospective approach. The guidance in ASU 2017-12 also provides transition relief to make it easier for entities to apply certain amendments to existing hedges (including fair value hedges) where the hedge documentation needs to be modified. The presentation and disclosure requirements of ASU 2017-12 should be applied prospectively. The amendments in this ASU are effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods. While the Company is still evaluating the timing of adoption, it currently does not expect this guidance to have a material impact on its consolidated financial statements and related disclosures. In June 2018, the FASB issued ASU No. 2018-07, “Compensation - Stock Compensation (Topic 718): Targeted Improvements to Non-employee Share-Based Payment Accounting” (“ASU 2018-07”). ASU 2018-07 expands the scope of Topic 718, Compensation-Stock Compensation, to include share-based payment transactions for acquiring goods and services from nonemployees. As a result, nonemployee share-based transactions will be measured by estimating the fair value of the equity instruments at the grant date, taking into consideration the probability of satisfying performance conditions. In addition, ASU 2018-07 also clarifies that any share-based payment awards issued to customers should be evaluated under ASC 606, Revenue from Contracts with Customers. The amendments in this ASU are effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods. Early adoption is permitted. The Company does not expect this guidance to have a material impact on its consolidated financial statements and related disclosures. In August 2018, the FASB issued ASU No. 2018-14, “Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20), to improve the effectiveness of disclosures in the notes to financial statements by facilitating clear communication of the information required by GAAP that is most important to users of each entity’s financial statements. The amendments in this ASU modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. Additionally, the amendments in this ASU remove disclosures that no longer are considered cost beneficial, clarify the specific requirements of disclosures, and add disclosure requirements identified as relevant. The amendments in this ASU are effective for fiscal years ending after December 15, 2020, for public business entities and for fiscal years ending after December 15, 2021, for all other entities. Early adoption is permitted for all entities. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and related disclosures.
