New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Note 12 — Recent Accounting Pronouncements On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118” ), which provides guidance on accounting for the tax effects of the Tax Cuts and Jobs Act (“TCJA”). SAB 118 provides a measurement period that should not extend beyond one year from the TCJA enactment date for companies to complete the accounting under ASC 740, Income Taxes. As of December 31, 2017, the Company has not completed its accounting related to the enactment of the Tax Act. However, the Company has made reasonable estimates of the effects on its income tax provision with respect to certain items, primarily the revaluation of its existing U.S. deferred tax balances as described in Note 8. In November 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2016 - 18: Statement of Cash Flows (Topic 230 ): Restricted Cash (“ASU 2016 - 18” ). The new standard requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The standard is effective for annual periods beginning after December 15, 2017, and interim periods within those annual reporting periods. Early adoption is permitted. The Company is currently evaluating the impact of this update on its consolidated financial statements. In August 2016, the FASB issued Accounting Standards Update No. 2016 - 15: Statement of Cash Flows (Topic 230 ): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016 - 15” ). The amendments in this update clarify how entities should classify certain cash receipts and cash payments on the Consolidated Statements of Cash Flows. The new guidance also clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. ASU 2016 - 15 will be effective for annual periods beginning after December 15, 2017, including interim periods within those annual reporting periods, but early adoption is permitted. The Company is currently evaluating the impact of this update on its consolidated financial statements. In March 2016, the FASB issued Accounting Standards Update No. 2016 - 09: Compensation - Stock Compensation (Topic 718 ): Improvements to Employee Share-Based Payment Accounting (“ASU 2016 - 09” ). The amendments in this update simplify several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in the statement of cash flows. ASU 2016 - 09 eliminates the requirement that excess tax benefits be realized as a reduction in current taxes payable before the associated tax benefit can be recognized as an increase in paid in capital. Under ASU 2016 - 09, these previously unrecognized deferred tax assets were recognized on a modified retrospective basis as of January 1, 2017, the start of the year in which the Company adopted ASU 2016 - 09. The U.S. federal and state net operating losses and credits recognized as of January 1, 2017 have been offset by a full valuation allowance. As a result, there is no cumulative-effect adjustment to retained earnings as of December 31, 2017. The Company elected not to change its policy on accounting for forfeitures and continues to estimate the total number of awards for which the requisite service period will not be rendered. The Company adopted ASU 2016 - 09 as of January 1, 2017. Adoption of ASU 2016 - 09 did not have a material impact on the Company’s consolidated financial statements. In February 2016, the FASB issued Accounting Standards Update No. 2016 - 02: Leases (Topic 842 ) (“ASU 2016 - 02” ). The amendments in this update require lessees, among other things, to recognize lease assets and lease liabilities on the balance sheet for all leases with terms greater than 12 months. This update also introduces new disclosure requirements for leasing arrangements. ASU 2016 - 02 will be effective for the Company in fiscal year 2019, but early adoption is permitted. The Company is currently evaluating the impact of this update on its consolidated financial statements. In January 2016, the FASB issued Accounting Standards Update No. 2016 - 01: Financial Instruments - Overall (Subtopic 825 - 10 ): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016 - 01” ). The amendments in this update address certain aspects of recognition, measurement, presentation and disclosure of financial instruments. In particular, the amendments in this update supersede, for public business entities, the requirement to disclose the methods and significant assumptions used in calculating the fair value of financial instruments required to be disclosed for financial instruments measured at amortized cost on the balance sheet. ASU 2016 - 01 will be effective for the Company in fiscal year 2018, but early adoption is permitted. The Company does not expect this standard to have a material impact on its consolidated financial statements. In July 2015, the FASB issued Accounting Standards Update No. 2015 - 11: Inventory (Topic 330 ): Simplifying the Measurement of Inventory (“ASU 2015 - 11” ), which changes the measurement principle for inventory from the lower of cost or market to the lower of cost and net realizable value. ASU 2015 - 11 defines net realizable value as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The update does not apply to inventory that is measured using last-in, first -out or the retail inventory method. The update applies to all other inventory, which includes inventory that is measured using first -in, first -out or average cost methods. The amendments in ASU 2015 - 11 are effective for the Company for fiscal years, and the interim periods within those years, beginning after December 15, 2016. The Company adopted ASU 2015 - 11 as of January 1, 2017. Adoption did not have a material impact on its consolidated financial statements. In May 2014, the FASB issued Standards Update No. 2014 - 09: Revenue from Contracts with Customers (Topic 606 ) (“ASU 2014 - 09” ), which provides a single, comprehensive revenue recognition model for all contracts with customers. The core principal of this ASU is that an entity should recognize revenue when it transfers 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. ASU 2014 - 09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In July 2015, the FASB finalized a one year delay in the effective date of this standard, which will now be effective January 1, 2018; however, early adoption is permitted any time after the original effective date, January 1, 2017. Companies can transition to the new standard under the full retrospective method or the modified retrospective method. The Company will adopt the standard effective January 1, 2018 and expects to utilize the modified retrospective methodology. The Company is continuing to evaluate the effect that the standard will have on its consolidated financial statements and related disclosures.
