Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018 - 13, "Fair Value Measurement (Topic 820 ): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement." ASU 2018 - 13 modified the disclosure requirements in Topic 820, "Fair Value Measurement," based on the FASB Concepts Statement, "Conceptual Framework for Financial Reporting - Chapter 8: Notes to Financial Statements," including consideration of costs and benefits. The guidance is effective for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the potential effects of this guidance on its consolidated financial statements. In June 2018, the FASB issued ASU No. 2018 - 07, “Compensation – Stock Compensation (Topic 718 ).” This ASU addresses share-based payment transactions for acquiring goods and services from nonemployees. An entity should apply the requirements of Topic 718 to nonemployee awards except for specific guidance on inputs to an option pricing model and the attribution of cost (that is, the period of time over which share-based payment awards vest and the pattern of cost recognition over that period). The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide ( 1 ) financing to the issuer or ( 2 ) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The adoption of this guidance did not have a material impact on our consolidated financial statements and related disclosures. In July 2017, the FASB issued ASU No. 2017 - 11, “Earnings Per Share (Topic 260 ), Distinguishing Liabilities from Equity (Topic 480 ), Derivatives and Hedging (Topic 815 ).” This ASU changes the classification analysis of certain equity-linked financial instruments (or embedded features) with down round features. As a result, a freestanding equity-linked financial instrument (or embedded conversion option) no longer would be accounted for as a derivative liability at fair value as a result of the existence of a down round feature. For freestanding equity classified financial instruments, the amendments require entities that present earnings per share (“EPS”) in accordance with Topic 260 to recognize the effect of the down round feature when it is triggered. The standard is effective for annual reporting periods beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted, including adoption in any interim period. We are currently assessing the impact the guidance will have on our consolidated financial statements and related disclosures. In May 2017, the FASB issued ASU No. 2017 - 09, “Compensation – Stock Compensation (Topic 718 ) Scope of Modification Accounting.” This ASU, which amends the scope of modification accounting for share-based payment arrangements, provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. The standard is effective for annual reporting periods, including interim periods within those annual reporting periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period. The adoption of this guidance did not have a material impact on our consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU No. 2017 - 04, “Intangibles —Goodwill and Other (Topic 350 ) Simplifying the Test for Goodwill Impairment.” This ASU simplifies several aspects of the accounting for goodwill impairment. The guidance requires an entity to perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The standard is effective for annual periods beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We are currently assessing the impact the guidance will have on our consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU No. 2016 - 02, “Leases.” This ASU requires lessees to recognize most leases on their balance sheets for the rights and obligations created by those leases. The guidance requires enhanced disclosures regarding the amount, timing, and uncertainty of cash flows arising from leases and will be effective for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The ASU requires adoption based upon a modified retrospective approach. The adoption of this guidance did not have a material impact on our consolidated financial statements and related disclosures. In May 2014, the FASB issued ASU No. 2014 - 09, “Revenue from Contracts with Customers.” This ASU will supersede most of the existing revenue recognition requirements in U.S. GAAP and will require entities to recognize revenue at an amount that reflects the consideration to which the Company expects to be entitled in exchange for transferring goods or services to a customer. The new standard also specifies new accounting for costs associated with obtaining or fulfilling contracts with customers and expands the required disclosures related to revenue and cash flows from contracts with customers. This new guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period and can be adopted either retrospectively to each prior reporting period presented or as a cumulative-effect adjustment as of the date of adoption, with early application not permitted. In August 2015, the FASB approved a one -year deferral of the effective date of this ASU. This standard became effective beginning with the first quarter 2018 and can be adopted either retrospectively to each prior reporting period presented or as a cumulative effect adjustment as of the date of adoption. We have adopted the guidance and currently it does not have a material impact on the financial statements as the Company does not have revenue. The requirements of the ASU will be followed when the Company does have revenue. There were various other accounting standards updates recently issued, most of which represented technical corrections to the accounting literature or were applicable to specific industries and are not expected to have a material impact on the Company's financial position, results of operations or cash flows.
