New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	NEW ACCOUNTING PRONOUNCEMENTS (ISSUED BUT NOT YET ADOPTED) In May 2014, the Financial Accounting Standards Board (the “FASB”) issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. This ASU is based on the principle that revenue is recognized to depict the transfer of 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. The ASU also 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, and assets recognized from costs incurred to obtain or fulfill a contract. The ASU allows either a “full retrospective” adoption, in which the standard is applied to all periods presented in the financial statements, or a “modified retrospective” adoption, in which the guidance is applied retrospectively only to the most current period presented in the financial statements, with the cumulative effect of initially applying the new standard being recognized as an adjustment to the opening balance of retained earnings at the date of initial application. As originally proposed, this guidance was effective for annual reporting periods beginning on or after December 15, 2016, including interim periods within that reporting period, and early adoption was not permitted. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which deferred the effective date of the new revenue recognition requirements to annual reporting periods beginning on or after December 15, 2017, including interim periods within that reporting period. Under ASU 2015-14, companies are permitted to adopt the guidance early, but no earlier than the original effective date outlined in ASU 2014-09. The FASB has issued a number of amendments to ASU 2014-09 that are intended to address implementation issues that were raised by stakeholders and provide additional practical expedients to reduce the cost and complexity of applying the new revenue standard. These amendments have the same effective date as ASU 2014-09. The Company adopted the new revenue standard effective January 1, 2018, following the “modified retrospective” method of adoption. In preparation for the adoption of the new standard, the Company established a project management team that was responsible for analyzing the impact of ASU 2014-09, and the related amendments, across all revenue streams. The project management team reviewed current accounting policies and practices, including a representative sample of contracts with customers, to identify potential differences that would result from applying the requirements under the new standard. The Company’s revenue is primarily generated from the sale of finished products to customers. Those sales predominantly contain a single delivery element and revenue is recognized at a single point in time when ownership, risks and benefits transfer. The timing of revenue recognition for these transactions was not significantly impacted by the new standard. Based on the implementation analysis performed, the Company has concluded that the adoption of the revised guidance will not have a material impact on its financial position, results of operations, or cash flows. While the impact of adoption will not be material, the Company expects to disclose the following adoption impacts in its Form 10-Q for the first quarter of 2018: (i) a reduction in net sales of less than 1% within the Environmental Solutions Group segment based on a revised “Principal vs. Agent” analysis resulting in a change from gross to net presentation, with a corresponding reduction in cost of sales, and (ii) presentation of a right of return asset and a refund liability on the Consolidated Balance Sheet, primarily related to parts and safety product sales for which a right of return exists, which is expected to increase current assets and current liabilities by less than 1%. The Company has also designed, and is in the process of implementing, the appropriate controls over gathering the information required to support the expanded disclosure requirements. The Company will provide these expanded revenue recognition disclosures based on the new qualitative and quantitative disclosure requirements of the standard in its Form 10-Q for the first quarter of 2018. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which requires organizations that are lessees in operating leases to recognize right-of-use assets and lease liabilities on the balance sheet and requires disclosure of key qualitative and quantitative information about leasing agreements by both lessors and lessees. For a lease to meet the requirements for accounting under a sale-leaseback transaction, it must meet the criteria for a sale in ASC 606, Revenue from Contracts with Customers. Entities are required to recognize and measure operating leases at the beginning of the earliest period presented using a modified retrospective approach. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company currently expects to adopt this guidance effective January 1, 2019. In preparation for the adoption of the new standard, the Company has established a project management team responsible for analyzing the impact of ASU 2016-02. The project management team is currently evaluating the impact that the adoption of this guidance will have on the Company’s consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Payments, which provides additional guidance on the financial statement presentation of certain activities in the statement of cash flows. The activities addressed by this guidance that may be relevant to the Company include cash payments for debt prepayment or debt extinguishment costs, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims and proceeds from the settlement of corporate-owned life insurance policies, and the application of the predominance principle. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. The amendments in this ASU should be applied using a retrospective transition method to each period presented. If it is impracticable to apply the amendments retrospectively for some of the issues, the amendments for those issues would be applied prospectively as of the earliest date practicable. The Company adopted this guidance effective January 1, 2018 and concluded that it did not have a material impact on its historical cash flow presentation. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740), Intra-Entity Transfers of Assets Other Than Inventory. This guidance requires the income tax consequences of an intra-entity transfer of an asset other than inventory to be recognized when the transfer occurs, instead of when the asset is sold to an outside party. The pronouncement is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within those annual reporting periods, with early adoption permitted. The amendments in this ASU should be applied on a modified retrospective basis, with an adjustment reflecting the cumulative effect of adoption being recorded directly to retained earnings as of the beginning of the period of adoption. The Company adopted this guidance effective January 1, 2018 and concluded that it did not have a material impact on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles – Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment, which eliminates the second step of the two-step quantitative approach for testing goodwill for potential impairment. An entity will therefore perform the goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, and recognize an impairment charge for the amount by which the carrying amount exceeds the fair value, not to exceed the total amount of goodwill allocated to the reporting unit. An entity still has the option to perform a qualitative assessment to determine if the quantitative impairment test is necessary. ASU 2017-04 is effective for fiscal years beginning after December 15, 2019 on a prospective basis, with early adoption permitted. The Company adopted this guidance effective January 1, 2018, and will apply the revised guidance prospectively to its future goodwill impairment tests. 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. This guidance requires that only the service cost component be included on the same line as other compensation costs on the statements of operations. All other components of net periodic pension cost should be reported separately from the service cost component and outside a subtotal of operating income. The guidance also specifies that only the service cost component of net periodic pension cost is eligible for capitalization. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. The amendments related to the presentation of the service cost and other components of net periodic pension cost included in this ASU should be applied retrospectively, whereas the amendments relating to the capitalization of the service cost component of net periodic pension cost should be applied prospectively. The Company adopted this guidance effective January 1, 2018. Although the retroactive application of requirements relating to the presentation of the service cost and other components of net periodic pension cost will have no overall impact on the Company’s Income before income taxes or Income from continuing operations in either of the years ended December 31, 2017 or 2016, Operating income for the years ended December 31, 2017 and 2016 is expected to increase by $6.5 million and $3.1 million, respectively, with Other (income) expense, net for the respective periods expected to decrease by the same amount. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities, which intends to better align risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and presentation of hedge results. The amendments also make certain targeted improvements to simplify the application of the hedge accounting guidance by easing certain documentation and assessment requirements. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The amendments in this ASU should be applied on a modified retrospective or prospective basis, depending on the area covered by the update. The Company adopted this guidance effective January 1, 2018 and concluded that it did not have a material impact on its consolidated financial statements. In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, that permits entities to reclassify tax effects stranded in accumulated other comprehensive income as a result of the 2017 Tax Act to retained earnings. ASU 2018-12 is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The amendments in this ASU may be applied retrospectively or in the period of adoption. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements. No other new accounting pronouncements issued, but not yet adopted, are expected to have a material impact on the Company’s results of operations, financial position or cash flow.
