New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements ASU 2017-12 In August 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("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. Early adoption is permitted. We do not expect the adoption of ASU 2017-09 to 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 2016-15 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. We do not expect the adoption of ASU 2016-15 to 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 still evaluating any potential impact that adoption of ASU 2016-02 may have on our financial position, results of operations or cash flows. 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. Except for the early application guidance specifically allowed in ASU 2016-01, early adoption is not permitted. We do not expect the adoption of ASU 2016-01 to have a material effect on our financial position, results of operations or cash flows. ASU 2015-17 In November 2015, the FASB issued ASU 2015-17, "Income Taxes (Topic 740) - Balance Sheet Classification of Deferred Taxes." ASU 2015-17 simplifies the presentation of deferred income taxes, and requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The amendments apply to all entities that present a classified statement of financial position and aligns the presentation of deferred income tax assets and liabilities with International Financial Reporting Standards. ASU 2015-17 is effective for public companies for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. We adopted this new accounting standard retrospectively in the first quarter of 2017. As of December 31, 2017 and December 31, 2016, we had $0.8 million and $2.1 million of current deferred tax assets that are now classified as noncurrent on the Consolidated Balance Sheets under this new accounting standard. ASU 2015-11 In July 2015, the FASB issued ASU No. 2015-11, "Simplifying the Measurement of Inventory (Topic 330)." ASU 2015-11 simplifies the accounting for the valuation of all inventory not accounted for using the last-in, first-out ("LIFO") method by prescribing that inventory be valued at the lower of cost and net realizable value. ASU 2015-11 is effective for financial statements issued for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016 on a prospective basis. The adoption of ASU 2015-11 in the first quarter of 2017 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 No. 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. We have elected the modified retrospective transition method and are currently evaluating the impact of adopting Topic 606 on January 1, 2018. We are currently preparing to implement changes to its accounting policies and controls to support the new revenue recognition and disclosure requirements.
