New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Standards	NEW ACCOUNTING STANDARDS Recently Adopted Accounting Standards under U.S. GAAP Effective January 1, 2018, we adopted Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers (Topic 606).” This update requires an entity to recognize revenue 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. See Note 4 to our condensed consolidated financial statements of this Quarterly Report for more information. In March 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-08, “Principal versus Agent Considerations (Reporting Revenue Gross versus Net)” which clarifies the implementation guidance on principal versus agent considerations. Entities are permitted to apply the amendments either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying the ASU recognized at the date of initial application. The adoption of this update did not have a material impact on our consolidated financial statements. Effective January 1, 2018, we adopted ASU No. 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities.” This update addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. Among other amendments, this update requires equity investments not accounted for under the equity method of accounting to be measured at fair value with changes in fair value recognized in net income. An entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. This updated guidance also simplifies the impairment assessment of equity investments without readily determinable fair values and eliminates the requirement to disclose significant assumptions and methods used to estimate the fair value of financial instruments measured at amortized cost. The updated guidance further requires the use of an exit price notion when measuring the fair value of financial instruments for disclosure purposes. All amendments are required to be adopted on a modified retrospective basis, with two exceptions. The amendments related to equity investments without readily determinable fair values and the requirement to use an exit price notion are required to be adopted prospectively. In February 2018 the FASB issued ASU No. 2018-03, “Technical Corrections and Improvements to Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” These amendments clarify the guidance in ASU No. 2016-01, on the following issues (among other things): Equity Securities without a Readily Determinable Fair Value-Discontinuation; Equity Securities without a Readily Determinable Fair Value- Adjustments; Forward Contracts and Purchase Options; Presentation Requirements for Certain Fair Value Option Liabilities; Fair Value Option Liabilities Denominated in a Foreign Currency; and Transition Guidance for Equity Securities without a Readily Determinable Fair Value. The amendments in this ASU are effective in conjunction with the adoption of ASU No. 2016-01. In March 2018 the FASB issued ASU No. 2018-04, “Investments-Debt Securities (Topic 320) and Regulated Operations (Topic 980): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 117 and SEC Release No. 33-9273.” This ASU supersedes SEC paragraphs pursuant to the SEC Staff Accounting Bulletin No. 117, which brings existing guidance into conformity with Topic 321, Investments-Equity Securities, and SEC Release No. 33-9273, which removed Regulation S-X Rule 3A-05, Special Requirements as to Public Utility Holding Companies. The adoption of these updates did not have a material impact on our consolidated financial statements. Effective January 1, 2018, we adopted ASU No. 2016-15, “Classification of Certain Cash Receipts and Cash Payments.” This update amends the existing guidance for the statement of cash flows and provides guidance on eight classification issues related to the statement of cash flows. The amendments in this ASU are required to be adopted retrospectively. For issues that are impracticable to adopt retrospectively, the amendments may be adopted prospectively as of the earliest date practicable. The adoption of this update did not have a material impact on our consolidated financial statements. Effective January 1, 2018, we adopted ASU No. 2016-16, “Intra-Entity Transfers of Assets Other Than Inventory.” This update requires that income tax consequences are recognized on an intra-entity transfer of an asset other than inventory when the transfer occurs. The amendments in this ASU are required to be adopted on a modified retrospective basis. The adoption of this update did not have a material impact on our consolidated financial statements. Effective January 1, 2018, we adopted ASU No. 2017-01, “Clarifying the Definition of a Business.” This update clarifies the definition of a business and provides a screen to determine when a set of assets and activities is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired or disposed of is concentrated in a single identifiable asset or a group of similar identifiable assets, such set of assets is not a business. The amendments in this ASU are required to be adopted prospectively. The adoption of this update did not have a material impact on our consolidated financial statements. Effective January 1, 2018, we adopted ASU No. 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” This update requires employers to disaggregate the service cost component from the other components of net benefit cost and disclose the amount of net benefit cost that is included in the income statement or capitalized in assets, by line item. The updated guidance requires employers to report the service cost component in the same line item(s) as other compensation costs and to report other pension-related costs (which include interest costs, amortization of pension-related costs from prior periods, and the gains or losses on plan assets) separately and exclude them from the subtotal of operating income. The updated guidance also allows only the service cost component to be eligible for capitalization when applicable. The amendments in this ASU are effective for us on January 1, 2018. The guidance requires adoption on a retrospective basis for the presentation of the service cost component and the other components of net periodic pension cost and net periodic post-retirement benefit cost in the income statement and on a prospective basis for the capitalization of the service cost component of net periodic pension cost and net periodic post-retirement benefit in assets. The adoption of this update did not have a material impact on our consolidated financial statements. Effective January 1, 2018, we adopted ASU No. 2017-09, “Scope of Modification Accounting.” This update provides clarity on when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. The amendments in this ASU are effective for us January 1, 2018 and are required to be adopted prospectively. The adoption of this update did not have a material impact on our consolidated financial statements. In March, 2018 the FASB issued ASU No. 2018-05, “Income Taxes (Topic 740)-Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118.” This ASU adds SEC paragraphs pursuant to the SEC Staff Accounting Bulletin No. 118, which expresses the view of the staff regarding application of Topic 740, Income Taxes, in the reporting period that includes December 22, 2017 - the date on which the Tax Cuts and Jobs Act (H.R.1, An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018) (the “Tax Cuts and Jobs Act”) was signed into law. The amendments in this ASU are effective upon issuance. The adoption of this update did not have a material impact on our consolidated financial statements. Recently Issued Accounting Standards under U.S. GAAP In February 2016, the FASB issued ASU No. 2016-02, “Leases.” This update requires that a lessee recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. Similar to current guidance, the update continues to differentiate between finance leases and operating leases, however, this distinction now primarily relates to differences in the manner of expense recognition over time and in the classification of lease payments in the statement of cash flows. The updated guidance leaves the accounting for leases by lessors largely unchanged from existing GAAP. Early application is permitted. Entities are required to use a modified retrospective adoption, with certain relief provisions, for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements when adopted. The guidance will become effective for us on January 1, 2019. The impacts that adoption of the ASU is expected to have on our consolidated financial statements and related disclosures are being evaluated. Additionally, we have not determined the effect of the ASU on our internal control over financial reporting or other changes in business practices and processes. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments-Credit Losses.” This update introduces a new model for recognizing credit losses on financial instruments based on an estimate of current expected credit losses. The updated guidance applies to (i) loans, accounts receivable, trade receivables, and other financial assets measured at amortized cost, (ii) loan commitments and other off-balance sheet credit exposures, (iii) debt securities and other financial assets measured at fair value through other comprehensive income, and (iv) beneficial interests in securitized financial assets. The amendments in this ASU are effective for us on January 1, 2020 and are required to be adopted on a modified retrospective basis. Early adoption is permitted. We are currently evaluating the impact of this ASU on our consolidated financial statements. In August 2017, the FASB issued ASU No. 2017-12, “Targeted Improvements to Accounting for Hedging Activities.” This update improves the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements and make certain targeted improvements to simplify the application of the hedge accounting guidance in current GAAP. The amendments in this update better align an entity's risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and presentation of hedge results. The amendments in this ASU are effective for us January 1, 2019. Early adoption is permitted. For cash flow and net investment hedges as of the adoption date, the guidance requires a modified retrospective approach. The amended presentation and disclosure guidance is required to be adopted prospectively. We are currently evaluating the impact of this ASU on our consolidated financial statements. On February 14, 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 (AOCI).” These amendments provide an option to reclassify stranded tax effects with AOCI to retained earnings in each period in which the effect of the change in the U.S. federal corporate tax rate in the Tax Cuts and Jobs Act (or portion thereof) is recorded. The ASU requires financial statement disclosures that indicate a description of the accounting policy for releasing income tax effects from AOCI; whether there is an election to reclassify the stranded income tax effects from the Tax Cuts and Jobs Act and information about the other income tax effects are reclassified. These amendments affect any organization that is required to apply the provisions of Topic 220, Income Statement-Reporting Comprehensive Income, and has items of other comprehensive income for which the related tax effects are presented in other comprehensive income as required by GAAP. The amendments in this ASU are effective for us January 1, 2019. We are currently evaluating the impact of this ASU on our consolidated financial statements.
