Recently Adopted Accounting Pronouncements and Recently Issued But Not Yet Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements 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. The primary provision of ASU No. 2018-02 allows for the reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. ASU No. 2018-02 also requires certain disclosures about stranded tax effects. ASU No. 2018-02 is effective for the Company on January 1, 2019, with early adoption permitted and will be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. The Company elected to adopt ASU No. 2018-02 during the first quarter of 2018. The adoption resulted in the reclassification of stranded tax amounts of $2,163 associated with net unrecognized losses from the Company's pension plans from accumulated other comprehensive loss to retained earnings. In May 2017, the FASB issued ASU No. 2017-09, Compensation-Stock Compensation (Topic 718). ASU No. 2017-09 provides clarity and guidance on which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. ASU No. 2017-09 was adopted by the Company on January 1, 2018 and it had no impact to the Company's condensed consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-07, Compensation-Retirement Benefits (Topic 715). ASU No. 2017-07 requires that an employer disaggregate the service cost component from the other components of net benefit cost. It also provides guidance on how to present the service cost component and the other components of net benefit cost in the income statement and what component of net benefit cost is eligible for capitalization. ASU No. 2017‑07 was adopted by the Company on January 1, 2018 and was applied retrospectively. As a result of the adoption, the Company reclassified the non-service cost components of the Company's pension expense for the three and nine months ended September 30, 2017 from other operating expenses to other income (expense), net. The Company elected to apply the practical expedient which allowed it to reclassify amounts disclosed previously in the benefits plan note as the basis for applying retrospective presentation for comparative periods, as the Company determined it was impracticable to disaggregate the cost components for amounts capitalized and amortized in those periods. See Note 3 for information on the impact of the adoption of ASU No. 2017-07. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805), Clarifying the Definition of a Business, which amends Topic 805 to interpret the definition of a business by adding guidance to assist in evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The Company adopted the new guidance on January 1, 2018 and it had no impact to the Company's condensed consolidated financial statements. In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, in order to clarify the Codification and to correct any unintended application of the guidance. The amendments in this update affected the guidance in ASC 606. ASC 606 was adopted by the Company on January 1, 2018 on a full retrospective basis, which required the Company to reflect the impact of the updated guidance for all periods presented. The adoption of ASC 606 did not have a material impact on the Company’s financial position or results of operations. See Note 3 for information on the impact of the adoption of ASC 606. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which requires that the statement of cash flows disclose the change during the period in the total of cash, cash equivalents, restricted cash and restricted cash equivalents. Restricted cash should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of period total amounts shown on the statement of cash flows. ASU No. 2016-18 provides specific guidance on the presentation of restricted cash in the statement of cash flows. ASU No. 2016-18 was adopted by the Company on January 1, 2018 and was applied retrospectively for all periods presented. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments which clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows. ASU No. 2016-15 also clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. The Company adopted the new guidance on January 1, 2018 and it had no impact to the Company's condensed consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities. ASU No. 2016-01 modifies how entities measure certain equity investments and also modifies the recognition of changes in the fair value of financial liabilities measured under the fair value option. Entities will be required to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income. For financial liabilities measured using the fair value option, entities will be required to record changes in fair value caused by a change in instrument-specific credit risk (own credit risk) separately in other comprehensive income. ASU No. 2016-01 was adopted by the Company on January 1, 2018 and it had no impact to the Company's condensed consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers ("ASC 606"), requiring an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASC 606 replaced most existing revenue recognition guidance in GAAP (See Note 3). Recently Issued But Not Yet Adopted Accounting Pronouncements In August 2018, the FASB issued ASU No. 2018-14, Changes to the Disclosure Requirements for Defined Benefit Plans, which amends ASC 715 to clarify certain disclosure requirements related to defined benefit pension and other postretirement plans. ASU 2018-14 becomes effective for the Company on January 1, 2022, although early adoption is permitted. The Company does not expect the adoption of ASU 2017-14 to have a material impact on its consolidated financial statements. Also in August 2018, the FASB issued ASU No. 2018-15, Customer’s Accounting for Implementation Costs in a Cloud Computing Arrangement That Is a Service Contract, which requires upfront implementation costs incurred in a cloud computing arrangement (or hosting arrangement) that is a service contract to be amortized to hosting expense over the term of the arrangement, beginning when the module or component of the hosting arrangement is ready for its intended use. ASU No. 2018-14 becomes effective for the Company on January 1, 2020, although early adoption is permitted. The Company is currently in the process of evaluating the impact that the adoption of ASU No. 2018-15 will have on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350). ASU No. 2017-04 simplifies the subsequent measurement of goodwill by removing the second step of the two‑step impairment test. The amendment requires an entity to perform its annual, or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. ASU No. 2017-04 becomes effective for the Company on January 1, 2020 with early adoption permitted and will be applied prospectively. In February 2016, the FASB issued ASU No. 2016-02, Leases, which increases transparency and comparability by recognizing a lessee’s rights and obligations resulting from leases by recording them on the balance sheet as lease assets and lease liabilities. The new guidance becomes effective for the Company on January 1, 2019. Although the Company has not yet completed its evaluation of the guidance, or quantified its impact, the Company believes the most significant impact will be the recognition of right of use assets and liabilities on its consolidated balance sheet. The Company expects its lease obligations designated as operating leases will be reported on the consolidated balance sheets upon adoption. The Company is also evaluating other potential lease arrangements of the business, including arrangements that have been previously disclosed as a contractual commitment. The Company is currently in the process of collecting and validating lease data and implementing a software solution. In addition, the Company is assessing practical expedients and policy elections offered by the standard, and is evaluating its processes and internal controls to meet the accounting, reporting and disclosure requirements.
