New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements ASU 2018-02 In February 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. ASU 2018-02 allows entities to reclassify accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (the “Act”). This update is effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. The update should be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the income tax rate change resulting from the Act is recognized. The early adoption of ASU 2018-02 on January 1, 2018 did not have a material effect on our financial position, results of operations or cash flows. ASU 2017-12 In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities." ASU 2017-12 refines and expands hedge accounting for both financial and commodity risks. Its provisions create more transparency around how economic results are presented, both on the face of the financial statements and in the footnotes. It also makes certain targeted improvements to simplify the application of hedge accounting guidance. ASU 2017-12 is effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2018, on a prospective basis. We do not expect the adoption of ASU 2017-12 to have a material effect on our financial position, results of operations or cash flows. ASU 2017-09 In May 2017, the FASB issued ASU 2017-09, "Compensation - Stock Compensation (Topic 718) - Scope of Modification Accounting." ASU 2017-09 provides clarity and is expected to reduce both diversity in practice and the cost and complexity when accounting for a change to the terms of a stock-based award. ASU 2017-09 is effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2017, on a prospective basis. The adoption of ASU 2017-09 on January 1, 2018 did not have a material effect on our financial position, results of operations or cash flows. ASU 2017-04 In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment." ASU 2017-04 simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. An entity should 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, if applicable. The loss recognized should not exceed the total amount of goodwill allocated to the reporting unit. The same impairment test also applies to any reporting unit with a zero or negative carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. ASU 2017-04 is effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2019, on a prospective basis. Early adoption is permitted for interim or annual goodwill impairment tests performed after January 1, 2017. We do not expect the adoption of ASU 2017-04 to have a material effect on our financial position, results of operations or cash flows. ASU 2016-18 In August 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230) - Restricted Cash." ASU 2016-18 reduces the diversity in practice in the classification and the presentation of restricted cash within an entity's statement of cash flows. ASU 2016-18 is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption permitted. The adoption of ASU 2016-18 on January 1, 2018 did not have a material effect on our financial position, results of operations or cash flows. ASU 2016-15 In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments." ASU 2016-15 addresses eight specific cash flow issues and how they should be reported on the statement of cash flows. ASU 2016-15 is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption permitted. The adoption of ASU 2016-15 on January 1, 2018 did not have a material effect on our financial position, results of operations or cash flows. ASU 2016-13 In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326)." ASU 2016-13 addresses accounting for credit losses for assets that are not measured at fair value through net income on a recurring basis. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods, with early adoption permitted for fiscal years beginning after December 15, 2018. We do not expect the adoption of ASU 2016-13 to have a material effect on our financial position, results of operations or cash flows. ASU 2016-02 In February 2016, the FASB issued ASU 2016-02, "Leases." ASU 2016-02 increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and requires disclosing key information about leasing arrangements. ASU 2016-02 is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods. We are currently evaluating the potential impact of the adoption of ASU 2016-02 on our consolidated financial statements. We currently expect the adoption of this standard to result in a material increase to the assets and liabilities on our consolidated balance sheets. ASU 2016-01 In January 2016, the FASB issued ASU 2016-01, “Financial Instruments - Overall (Subtopic 825-10).” ASU 2016-01 enhances the reporting model for financial instruments to provide users of financial statements with more decision-useful information by addressing certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The amendments simplify certain requirements and also reduce diversity in current practice for other requirements. ASU 2016-01 is effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of ASU 2016-01 on January 1, 2018 did not have a material effect on our financial position, results of operations or cash flows. ASU 2014-09, ASU 2016-10 and ASU 2016-12 In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU 2014-09, as amended, affects any entity using U.S. GAAP that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards (e.g., insurance contracts or lease contracts). ASU 2014-09, as amended, is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. In April 2016, the FASB issued ASU 2016-10, "Revenue from Contracts with Customers (Topic 606) - Identifying Performance Obligations and Licensing." ASU 2016-10 clarifies aspects of Topic 606 related to identifying performance obligations and the licensing implementation guidance, while retaining the related core principles for those areas. The effective date and transition requirements for ASU 2016-10 are the same as the effective date and transition requirements in ASU 2014-09. In May 2016, the FASB issued ASU 2016-12, "Revenue from Contracts with Customers (Topic 606) - Narrow-Scope Improvements and Practical Expedients." ASU 2016-12 clarifies aspects of Topic 606 related to the guidance on assessing collectibility, presentation of sales taxes, non-cash consideration, and completed contracts and contract modifications. The effective date and transition requirements for ASU 2016-12 are the same as the effective date and transition requirements in ASU 2014-09. The standards permit either the retrospective or the modified retrospective (cumulative effect) transition method. On January 1, 2018, we adopted the new accounting standard Accounting Standards Codification ("ASC") 606, "Revenue from Contracts with Customers" and all the related amendments to all contracts using the modified retrospective method. We recognized the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of accumulated deficit. We expect the impact of the adoption of the new standard to be immaterial to our net income on an ongoing basis. See also Note 8.
