New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements New Accounting Pronouncements Adopted In March 2016, the Financial Accounting Standards Board ("FASB") issued an Accounting Standards Update ("ASU"), Improvements to Employee Share-Based Payment Accounting, which simplified several areas of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. The new standard requires excess tax benefits or deficiencies for share-based payments to be recognized as income tax benefit or expense, rather than within additional paid-in capital, when the awards vest or are settled. Furthermore, cash flows related to excess tax benefits are required to be classified as operating activities in the statement of cash flows rather than financing activities. We adopted these amendments effective December 31, 2016, the first day of our 2017 year. We have elected to account for forfeitures of stock-based awards as they occur and have adopted on a modified retrospective basis, as such, we recorded a cumulative effect adjustment of $0.2 million (pre-tax) to reduce retained earnings and increase additional paid-in capital as of December 31, 2016, the first day of our 2017 year. 2. Recently Issued Accounting Pronouncements (continued) The new standard also requires the presentation of cash paid to taxing authorities at settlement arising from the withholding of shares from employees be classified as a financing activity on the statement of cash flows. We adopted these amendments, effective December 31, 2016, the first day of our 2017 year, on a retrospective basis. In July 2015, the FASB issued an ASU, Simplifying the Measurement of Inventory. The core principal of the guidance is that an entity should measure inventory at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This guidance does not apply to inventory that is being measured using the Last-In, First-Out (LIFO) or the retail inventory method. The Company adopted this guidance on December 31, 2016, the first day of our 2017 year, and determined there were no changes to disclosure, financial statement presentation, or valuation of inventory as a result of adoption. New Accounting Pronouncements Not Yet Adopted In March 2017, the FASB issued an ASU, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU requires that the service cost component of net periodic benefit costs from defined benefit and other postretirement benefit plans be included in the same Statement of Earnings captions as other compensation costs arising from services rendered by the covered employees during the period. The other components of net benefit cost will be presented in the Statement of Earnings separately from service costs. Following adoption, only service costs will be eligible for capitalization into manufactured inventories, which should reduce diversity in practice. This ASU will be effective for us beginning the first day of our 2018 fiscal year. As this ASU only affects presentation and disclosure we do not anticipate a significant impact of adoption on our financial condition, results of operations and cash flows. In February 2017, the FASB issued an ASU, Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets: Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets, which clarifies the scope of asset decrecognition and adds further guidance for recognizing gains and losses from the transfer of nonfinancial assets in contracts with non-customers. This ASU will be effective for us beginning the first day of our 2018 fiscal year. Early adoption is permitted. We are evaluating the impact of adoption of this ASU on our financial condition, results of operations and cash flows, and as such, we are not able to estimate the effect the adoption of the new standard will have on our financial statements. In January 2017, the FASB issued an ASU, Business Combinations: Clarifying the Definition of a Business, which adds guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This ASU will be effective for us beginning the first day of our 2018 fiscal year. Early adoption is permitted. We do not expect this ASU to have an impact until a valid transaction takes place. In January 2017, the FASB issued an ASU, Simplifying the Test for Goodwill Impairment, which removes the requirement to compare the implied fair value of goodwill with its carrying amount as part of step 2 of the goodwill impairment test. The ASU permits an entity to perform its annual, or interim, 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 reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. This ASU will be effective for us beginning the first day of our 2020 fiscal year. Early adoption is permitted. We are evaluating the impact of adoption of this ASU on our financial condition, results of operations and cash flows, and as such, we are not able to estimate the effect the adoption of the new standard will have on our financial statements. In October 2016, the FASB issued an ASU, Intra-Entity Transfers of Assets Other Than Inventory, which will require companies to recognize the income tax effects of intra-entity sales and transfers of assets other than inventory, but particularly those asset transfers involving intellectual property, in the period in which the transfer occurs. The ASU will be effective for us beginning the first day of our 2018 fiscal year. 2. Recently Issued Accounting Pronouncements (continued) The guidance requires modified retrospective adoption. We are evaluating the impact of adoption of this ASU on our financial condition, results of operations and cash flows, and as such, we are not able to estimate the effect the adoption of the new standard will have on our financial statements. In August 2016, the FASB issued an ASU, Classification of Certain Cash Receipts and Cash Payments, which addresses eight specific cash flow issues in an effort to reduce diversity in practice. This ASU will be effective for us beginning the first day of our 2018 fiscal year. Early adoption is permitted. We are evaluating the impact of adoption of this ASU on our cash flows, and as such, we are not able to estimate the effect that the adoption of this ASU will have on reclassifications on our consolidated statement of cash flows. In February 2016, the FASB issued an ASU, Leases, which requires a dual approach for lessee accounting under which a lessee would account for leases as finance leases or operating leases. Both finance leases and operating leases will result in the lessee recognizing a right-of use asset and a corresponding lease liability. For finance leases, the lessee would recognize interest expense and amortization of the right-of-use asset, and for operating leases, the lessee would recognize a straight-line total lease expense. The guidance also requires qualitative and specific quantitative disclosures to supplement the amounts recorded in the financial statements so that users can understand more about the nature of an entity’s leasing activities, including significant judgments and changes in judgments. This ASU will be effective for us beginning the first day of our 2019 fiscal year. Early adoption is permitted. We are evaluating the impact of adoption of this ASU on our financial condition, results of operations and cash flows, and as such, we are not able to estimate the effect the adoption of the new standard will have on our financial statements. In May 2014, the FASB issued an ASU, Revenue From Contracts with Customers, and has subsequently issued several supplemental and / or clarifying ASUs (collectively "ASC 606"), which prescribes a comprehensive new revenue recognition standard that will supersede existing revenue guidance. ASC 606's core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The standard outlines a five step model, whereby revenue is recognized as performance obligations within a contract are satisfied. The standard also requires new, expanded disclosures regarding revenue recognition. ASC 606 will be effective for us beginning the first day of our 2018 fiscal year. Early adoption is not permitted. We are evaluating the impact of adoption of ASC 606 on our financial condition, results of operations and cash flows, and as such, we are not able to reasonably estimate the effect that the adoption of the new standard will have on our financial statements. We have commenced an initial analysis and have a team in place to analyze the impact of ASC 606. This includes reviewing current accounting policies and practices to identify potential differences that would result from applying the requirements under the new standard. The standard permits the use of either the retrospective or modified retrospective transition method. We will adopt the new standard using the modified retrospective transition method, under which the cumulative effect of initially applying the new guidance is recognized as an adjustment to the opening balance of retained earnings on the first day of our 2018 fiscal year.
