New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to nonemployee share-based payment accounting, which supersedes ASC 505-50, Accounting for Distributions to Shareholders with Components of Stock and Cash, and expands the scope of ASC 718 to include all share-based payment arrangements related to the acquisition of goods and services from both nonemployees and employees. As a result, most of the guidance in ASC 718 associated with employee share-based payments, including most of its requirements related to classification and measurement, applies to nonemployee share-based payment arrangements. The ASU is effective for annual periods beginning after December 15, 2018, and the interim periods within those fiscal years with early adoption permitted after the entity has adopted ASC 606. We are evaluating the effect that this will have on our consolidated financial statements and related disclosures. In March 2018, the FASB issued ASU 2018-05, Income Taxes (Topic 740)—Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118 ("SAB 118"). This ASU amends certain Securities and Exchange Commission (SEC) material in Topic 740 for the income tax accounting implications of the recently issued Tax Reform. This guidance clarifies the application of Topic 740 in situations where a registrant does not have the necessary information available, prepared, or analyzed in reasonable detail to complete the accounting under Topic 740 for certain income tax effects of Tax Reform for the reporting period in which Tax Reform was enacted. See Note I, Income Taxes, for a discussion of the impacts of SAB 118 and this ASU. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU allows for reclassification of stranded tax effects on items resulting from the change in the corporate tax rate as a result of H.R. 1, originally known as the Tax Cuts and Jobs Act of 2017, from accumulated other comprehensive income to retained earnings. Tax effects unrelated to H.R. 1 are permitted to be released from accumulated other comprehensive income using either the specific identification approach or the portfolio approach, based on the nature of the underlying item. ASU 2018-02 is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. We are evaluating the effect that this will have on our consolidated financial statements and related disclosures. In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting, which provides clarified guidance on applying modification accounting to changes in the terms or conditions of a share-based payment award. This ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017, with early adoption permitted. This change is required to be applied prospectively to an award modified on or after the adoption date. This standard was adopted as of January 1, 2018 and did not have a material impact on our consolidated financial statements and related disclosures. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which provides clarified guidance on the classification of certain cash receipts and payments in the statement of cash flows. This ASU is effective for annual periods beginning after December 15, 2017, including interim reporting periods within those annual reporting periods. This change is required to be applied using a retrospective transition method to each period presented. Early adoption is permitted. This standard was adopted as of January 1, 2018 and did not have a material impact on our consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU 2016-02, Leases, which requires all operating leases to be recorded on the balance sheet. The lessee will record a liability for its lease obligations (initially measured at the present value of the future lease payments not yet paid over the lease term, and an asset for its right to use the underlying asset equal to the lease liability, adjusted for lease payments made at or before lease commencement). This ASU is effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. This change is required to be applied using a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. Full retrospective application is prohibited. We are evaluating the impact that adoption of ASU 2016-02 will have on our consolidated financial statements, but expect an increase in assets and liabilities on our consolidated balance sheets at adoption for the recording of right-of-use assets and corresponding lease liabilities. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). We adopted ASU 2014-09 and its related amendments (collectively known a “ASC 606”) effective on January 1, 2018 using the modified retrospective method. Please see Note C, Revenue from Contracts with Customers, for the required disclosures related to the impact of adopting this standard and a discussion of our updated policies related to revenue recognition and accounting for costs to obtain and fulfill a customer contract.
