Recent accounting pronouncements [Abstract]
Recent accounting pronouncements [Text Block]	Recent accounting pronouncements. In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842). This ASU requires entities to recognize assets and liabilities for most leases on their balance sheets. It also requires additional qualitative and quantitative disclosures to help investors and other financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases. ASU No. 2016-02 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the effect that this standard will have on the consolidated financial statements and related disclosures. In April 2015, the FASB issued authoritative guidance to simplify the balance sheet presentation of debt issuance costs. Under the new guidance, debt issuance costs is presented as a reduction of the carrying amount of the debt liability. The guidance was effective for the Company beginning February 1, 2016 and was applied retrospectively for all periods presented. The Company adopted this guidance and it did not have a material impact on the Company's financial statements. In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40) - Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”). ASU 2014-15 provides guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. ASU 2014-15 is effective for annual periods ending after December 15, 2016, and for annual periods and interim periods thereafter. Early adoption is permitted. The adoption of ASU 2014-15 is not expected to have an impact on the Company’s consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. This new standard provides for a single comprehensive model and supersedes most current revenue recognition guidance, including industry specific guidance, and provides for enhanced disclosure requirements. The objective of the new guidance is to improve the consistency, comparability and usefulness to users of financial statements. On April 1, 2015, FASB decided to defer the effective date of the new revenue standard by one year. As a result, public entities would apply the new revenue standard for fiscal years, and interim periods within those years, beginning after December 15, 2017. ASU 2014-09 provides for two implementation methods (1) full retrospective application to each prior period or (2) modified retrospective application with the cumulative effect as of the date of adoption. The Company is evaluating the financial statement impacts of the guidance in this ASU and determining which transition method will be utilized.
