New Accounting Standards [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606). The amendments in this update will replace most of the existing GAAP revenue recognition guidance. The core principle of this ASU is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. The ASU requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments, and changes in judgments. The Company will adopt the ASU on January 1, 2018 using the modified retrospective approach and with the cumulative effect of initially applying the update recognized as an adjustment to the opening balance of “Accumulated deficit” on the Consolidated Balance Sheets. The Company has completed an evaluation of its revenue activities against the requirements of the ASU. During the evaluation, the Company identified certain contractual arrangements involving customer specific application engineering primarily in the Energy segment that will, in certain circumstances, meet the criteria for revenue recognition over time under the new standard. The contracts meeting this criteria are those with no alternative use and terms and conditions which specify the recovery of cost plus a reasonable margin for work performed to-date in the event of cancellation for convenience. Currently, revenue on these arrangements is recognized when each performance obligation is complete or substantially complete, provided all other revenue recognition criteria have been met. The Company has completed the process of updating its information systems to comply with the requirements of the ASU. Based upon our assessment of contracts in process as of December 31, 2017, the Company does not anticipate a material cumulative adjustment to opening “Accumulated deficit” on the Consolidated Balance Sheets as a result of adoption. Historically, a significant portion of the Energy segment project revenue has been recognized when projects ultimately ship in the Company’s fourth quarter. An effect of the adoption of the ASU will be to accelerate a portion of this revenue to earlier quarters for those contracts qualifying for revenue recognition over time. The magnitude of the effect in a given quarter will be dependent upon the number and magnitude of active highly engineered project contracts with terms and conditions which require revenue recognition over time. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The amendments in this update will replace most of the existing GAAP lease accounting guidance in order to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The ASU is effective for public companies beginning in the first quarter of 2019. The ASU requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. This approach allows a Company to elect to use a number of optional practical expedients. The Company is currently assessing the impact of this ASU on its consolidated financial statements and evaluating the method of adoption. In March 2017, the FASB issued ASU 2017-07, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This update was intended to improve the presentation of net periodic pension costs and net periodic postretirement benefit costs in the financial statements. The amendments in this ASU requires the Company 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 a subtotal of operating income. If a separate line item or items are not used to present the other components of net benefit cost, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. The amendment allows only the service cost component of net benefit cost to be eligible for capitalization. The ASU is effective for public companies for the annual and interim reporting periods of 2018. Disclosures of the nature of and reason for the change in accounting principle are required in the first interim and annual periods of adoption. The amendments in this ASU are to be applied retrospectively for presentation in the income statement and prospectively for the capitalization of the service cost component of net periodic pension cost and net periodic postretirement benefit in assets. A practical expedient allows the Company to use the amount disclosed in its pension and other postretirement benefit plan note for the prior comparative periods as the estimation basis for applying the retrospective presentation requirements. Disclosure must be made if the practical expedient was used. The Company does not expect this ASU to have a material impact on the Company’s consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This update was intended to improve the financial reporting of hedging relationships to better portray the economic results of the Company’s risk management activities in its financial statements through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. The amendments in this ASU require the Company to present the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is reported. This allows users of the financial statements to better understand the results and costs of the Company’s hedging program. The Company is required to apply the amendments to cash flow and net investment hedge relationships that exist on the date of adoption using a modified retrospective approach. The presentation and disclosure requirements must be applied prospectively. The effective date for adoption is for annual and interim periods beginning after December 15, 2018. This will require adoption in the first quarter of fiscal year 2019. The Company is currently assessing the impact of this ASU on its consolidated financial statements and evaluating the timing of adoption.
