Organization, Consolidation and Presentation of Financial Statements [Abstract]
New Accounting Standards	New Accounting Standards—In May 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting, which provided clarity on which changes to the terms or conditions of share-based payment awards require an entity to apply the modification accounting provisions required in Topic 718. This standard is effective for us beginning January 1, 2018 (with early adoption permitted, including adoption in any interim period for which financial statements have not yet been issued). We do not expect the adoption of this standard will have a material impact on our financial statements. 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, which aims to improve the presentation of net periodic pension cost. Under current accounting standards, all components of net periodic pension costs are aggregated and reported in cost of sales or selling, general and administrative expenses in the financial statements. Under the new standard we will be required to report only the service cost component in cost of sales or selling, general and administrative expenses; and the other components of net periodic pension costs (which include interest costs, expected return on plan assets and amortization of net loss) will be required to be presented in non-operating expenses. The presentation requirement of this standard is effective for us beginning January 1, 2018 (with early adoption permitted) using a retrospective transition approach and provides for certain practical expedients. We do not expect the adoption of this standard will have a material impact to our financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which amends the impairment model by requiring entities to use a forward-looking approach, based on expected losses, to estimate credit losses on certain types of financial instruments, including trade receivables. This standard is effective for us beginning January 1, 2020, with early adoption permitted. We are currently evaluating the impact of this standard on our financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which will require, among other items, lessees to recognize a right-of-use asset and a lease liability for most leases. The standard also requires disclosures by lessees and lessors about the amount, timing and uncertainty of cash flows arising from leases. The accounting applied by a lessor is largely unchanged from that applied under the current standard. This standard is effective for us beginning January 1, 2019 (with early adoption permitted) using a modified retrospective transition approach and provides for certain practical expedients. In September 2017, the FASB issued ASU No. 2017-13, Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842), which provided additional implementation guidance on the previously issued ASU. We are currently evaluating the impact of this standard on our financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which impacts virtually all aspects of an entity’s revenue recognition. The core principle of the new standard is that revenue should be recognized 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. During 2016 and 2017, the FASB issued several amendments to the standard, including clarification to the guidance on reporting revenues as a principal versus an agent, identifying performance obligations, accounting for intellectual property licenses, assessing collectability, presentation of sales taxes, impairment testing for contract costs, disclosure of performance obligations and provided additional implementation guidance. The new standard will also require additional disclosures intended to provide users of financial statements comprehensive information about the nature, amount, timing and uncertainty of revenue and cash flows from customer contracts. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented and the cumulative effect of applying the standard would be recognized at the earliest period shown, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. We currently anticipate adopting this standard beginning January 1, 2018 using the modified retrospective method. We are currently completing our assessment and quantifying the impact of the new revenue standard on our financial statements and related disclosures. We expect recognition of revenue for a majority of customer contracts to remain substantially unchanged. However, we are continuing to assess all potential impacts of the standard and we currently believe the more significant impacts relate to certain customer contracts that will be recognized over time, accounting for any required deferral of commissions and changes to the timing of recognition of revenue and costs related to certain warranty arrangements. We have identified, and are in the process of implementing, appropriate changes to our processes, systems and controls to support recognition and disclosure under the new standard. Furthermore, we anticipate that our disclosures will be expanded to meet the new standard’s disclosure objectives.
