Recently Adopted and Issued Accounting Standards	Recently Adopted Accounting Standards In February 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which requires an entity to disclose its accounting policy related to releasing income tax effects from accumulated other comprehensive income (loss), whether it has elected to reclassify the stranded tax effects in accumulated other comprehensive income (loss) to retained earnings in the statement of shareholder’s equity and if it has elected to reclassify the stranded tax effects in accumulated other comprehensive income (loss) to retained earnings, what the reclassification encompasses. The Company early adopted this standard on a retrospective basis on January 1, 2018. The adoption resulted in an increase of $6.4 million to Retained earnings and a corresponding change of $6.4 million to Accumulated other comprehensive income (loss) at January 1, 2018. In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business, which clarifies the definition of a business and assists entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. Under this guidance, when substantially all of the fair value of gross assets acquired is concentrated in a single asset or group of similar assets, the assets acquired would not represent a business. In addition, in order to be considered a business, an acquisition would have to include at a minimum an input and a substantive process that together significantly contribute to the ability to create an output. The amended guidance also narrows the definition of outputs by more closely aligning it with how outputs are described in FASB guidance for revenue recognition. The Company adopted this standard on January 1, 2018. The adoption of this standard did not have a material impact on our condensed consolidated financial statements. In October 2016, the FASB issued ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory, which amends Accounting Standards Codification (“ASC”) 740, Income Taxes. This ASU requires that the income tax consequences of an intra-entity asset transfer other than inventory are recognized at the time of the transfer. An entity will continue to recognize the income tax consequences of an intercompany transfer of inventory when the inventory is sold to a third party. The Company adopted this standard on a modified-retrospective basis on January 1, 2018. The adoption resulted in a decrease of $7.3 million to Other current assets, a decrease of $6.7 million to Deferred income taxes and a decrease of $0.6 million to Retained earnings at January 1, 2018. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments (a consensus of the FASB Emerging Issues Task Force). This ASU addresses the following eight specific cash flow issues: Debt prepayment or debt extinguishment costs; 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; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies (including bank-owned life insurance policies); distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. The Company adopted this standard on January 1, 2018. The adoption of this standard did not have a material impact on our condensed consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which replaces numerous requirements in U.S. GAAP, including industry-specific requirements, and provides companies with a new five-step model for recognizing revenue from contracts with customers. Under ASU 2014-09, an entity 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. This ASU also requires disclosures sufficient to enable users to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers, including qualitative and quantitative disclosures about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. The FASB has also issued the following standards which clarify ASU 2014-09 and have the same effective date as the original standard: ASU 2016-08, Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net); ASU 2016-10, Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing; ASU 2016-12, Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients; and ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. In 2016, we established an implementation team and analyzed the impact of the standard by surveying business units and performing extensive contract reviews to identify potential differences that may result from applying the requirements of the new standard. The contract reviews generally supported the recognition of revenue at a point in time, which is consistent with the current revenue recognition model used by most of our business units. As a result, revenue recognition remains unchanged under the new standard. For our business units that currently recognize revenue under a percentage of completion model, revenue recognition also remains unchanged as the contract reviews supported the recognition of revenue over time. The Company has implemented the appropriate changes to its processes, systems and controls to comply with the new guidance. The Company adopted this standard on January 1, 2018 using the modified retrospective approach applied to contracts that were not completed as of January1, 2018. The adoption of this standard did not have an impact on our condensed consolidated financial statements. The Company elected the following practical expedients: significant financing component, sales tax presentation, contract costs, shipping and handling activities, and disclosures. See Note 4 for further details on revenue. Recently Issued Accounting Standards In February 2016, the FASB issued ASU 2016-02, Leases, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The standard introduces a new lessee model that will require most leases to be recorded on the balance sheet and eliminates the required use of bright line tests in current U.S. GAAP for determining lease classification. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. This standard is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Companies are permitted to adopt the standard early and a modified retrospective application is permitted. The new guidance requires adoption on a retrospective basis unless it is impracticable to apply, in which case the Company would be required to apply the amendments prospectively as of the earliest date practicable.The Company is currently evaluating the impact of adopting the new guidance on its condensed consolidated financial statements.
