Accounting Changes and Error Corrections [Abstract]
Recently Issued Accounting Pronouncements	In May 2014, the Financial Accounting Standards Board (“FASB”) issued accounting guidance designed to enhance comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets. The core principle of the guidance is that revenue recognized from a transaction or event that arises from a contract with a customer should reflect the consideration to which an entity expects to be entitled in exchange for goods or services provided. To achieve that core principle the new guidance sets forth a five-step revenue recognition model that will need to be applied consistently to all contracts with customers, except those that are within the scope of other topics in the ASC. Also required are new disclosures to help users of financial statements better understand the nature, amount, timing and uncertainty of revenues and cash flows from contracts with customers. The new disclosures include qualitative and quantitative information about contracts with customers, significant judgments made in applying the revenue guidance, and assets recognized related to the costs to obtain or fulfill a contract. During 2016, the FASB issued amendments to this new guidance that provides clarification, technical corrections and practical expedients. Topics of potential relevance to the Company include principal versus agent considerations, collectability, presentation of sales tax from customers, contract modifications at transition and accounting transition. These new requirements became effective on January 1, 2018 and did not have a material impact on our condensed consolidated financial statements. We adopted the new standard using the modified retrospective method. We have implemented appropriate changes to the business processes, controls and control activities to support recognition, presentation and disclosure under the new standard for the first quarter of 2018, however, we have not made any significant changes to our existing systems as a result of this new standard. In February 2016, the FASB issued accounting guidance that requires assets and liabilities arising from leases to be recorded on the balance sheet. Additional disclosures are required regarding the amount, timing, and uncertainty of cash flows from leases. This new guidance will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, and is to be applied using a modified retrospective approach. Early adoption is permitted. In July 2018, the FASB issued an amendment which would allow entities to initially apply this new standard at the adoption date and recognize a cumulative effect adjustment to the the opening balance of retained earnings. The Company expects to adopt this standard using this transition method. We have made significant progress in evaluating our existing lease contracts and accounting policies to determine the impact this standard will have on the condensed consolidated financial statements and related disclosures. The implementation of this standard will result in the addition of right-of-use assets and lease liabilities on our balance sheet, however, we have not determined the materiality at this time. In addition, we are in the process of reviewing the impact of this standard on our current business processes and are making progress on implementing changes to and controls to support recognition and disclosure under this new standard. In October 2016, the FASB issued accounting guidance that eliminated the deferral of tax effects of intra-entity asset transfers other than inventory. As a result, the tax expense from the intercompany sale of assets, other than inventory, and associated changes to deferred taxes will be recognized when the sale occurs even though the pre-tax effects of the transaction have not been recognized as they are eliminated in consolidation. This guidance was effective using the modified retrospective method as of January 1, 2018, which resulted in a $11.2 million cumulative adjustment to decrease Retained earnings and is not reflected in periods prior to this date. In November 2016, the FASB issued accounting guidance that requires restricted cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning and end of period total amounts shown on the statement of cash flows. This guidance became effective on January 1, 2018 and did not have a significant impact on our financial statements. In January 2017, the FASB issued accounting guidance to clarify the definition of a business for determining whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This guidance became effective on January 1, 2018 and did not have a significant impact on our financial statements. In January 2017, the FASB issued accounting guidance to simplify the accounting for goodwill impairment. The guidance removes Step 2 of the goodwill impairment test, which requires a reporting unit to calculate the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit has been acquired in a business combination. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance will remain unchanged. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. This guidance will be effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, and is to be applied on a prospective basis. Early adoption is permitted for goodwill impairment tests performed after January 1, 2017. We do not expect this guidance to have a significant impact on our financial statements. In March 2017, the FASB issued accounting guidance that changes the presentation of net periodic pension and postretirement benefit cost (“net benefit cost”) in the income statement. This new guidance requires service cost to be presented as part of operating income (expense) and all other components of net benefit cost are to be shown outside of operations. This guidance became effective on January 1, 2018 and did not have a significant impact on our financial statements. The prior year consolidated statements of income have been recast to conform to the current presentation required by this guidance. See Note 12, “Pension Plans and Other Postretirement Benefits,” for additional details. In May 2017, the FASB issued accounting guidance to clarify when to account for a change to the terms or conditions of a share-based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. This new guidance became effective on January 1, 2018 and did not have a significant impact on our financial statements. In August 2017, the FASB issued accounting guidance to better align an entity’s risk management activities with hedge accounting, simplify the application of hedge accounting, and increase transparency as to the scope and results of hedging programs. This guidance will make more financial and nonfinancial hedging strategies eligible for hedge accounting. It also amends the presentation and disclosure requirements and changes how companies assess effectiveness. This new guidance will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, and is to be applied on a prospective basis. Early adoption is permitted. We currently do not expect this guidance to have a significant impact on our financial statements. In February 2018, the FASB issued accounting guidance that will give companies the option to reclassify stranded tax effects caused by the TCJA from accumulated other comprehensive income to retained earnings. This new guidance will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. Entities will have the option to apply this guidance retrospectively or to record the reclassification as of the beginning of the period of adoption. We are currently assessing the impact of this new guidance on our financial statements. In March 2018, the FASB issued additional guidance pursuant to the issuance of SAB 118, that provides clarification for a company’s ability to comply with the accounting requirements for the income tax effects of the TCJA in the period of enactment, effective immediately. SAB 118 allows disclosure that timely determination of some or all of the income tax effects from the TCJA are incomplete by the due date of the financial statements and if possible to provide a reasonable estimate. We have accounted for the tax effects of the TCJA under the guidance of SAB 118, on a provisional basis. Our accounting for certain income tax effects is incomplete, but we have determined reasonable estimates for those effects and have recorded provisional amounts in our condensed consolidated financial statements.
