Description of New Accounting Pronouncements Not yet Adopted [Text Block]	Note 12 - Recent accounting pronouncements In June 2018, the FASB issued an update to Topic 718, which is intended to reduce costs and complexity, and improve financial reporting for share-based payments issued to non-employees. ASU No. 2018 - 07 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The Company has evaluated the effect that this ASU will have on its consolidated financial statements and related disclosures, and has determined that this ASU does not have a material impact on the Company's results of operations or financial position. In March 2017, the FASB issued authoritative guidance which changes the income statement presentation of the components of net periodic benefit cost related to defined benefit pension and other post-retirement plans. The primary change under the new guidance is that only the service cost component of net periodic benefit cost should be included in operating income and is eligible for capitalization as an asset. The other components of net periodic benefit cost, such as interest cost, the expected return on assets, and amortization of actuarial gains and losses and prior service cost, should be presented below operating income. The guidance was effective for the Company starting February 1, 2018 and has been applied retrospectively to the presentation of net periodic benefit cost and prospectively to the capitalization of service cost. The adoption of this guidance did not have a material impact on the Company's results of operations or financial position. In October 2016, the FASB issued authoritative guidance requiring the recognition of the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs rather than when transferred to a third party as required under the current guidance. The new guidance was effective for the Company beginning February 1, 2018. The adoption of this guidance did not have a material impact on the Company's results of operations or financial position. In February 2016, the FASB issued 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 its consolidated financial statements and related disclosures. In May 2014, the FASB issued ASU No. 2014 - 09, "Revenue from Contracts with Customers ("Topic 606" )", with several clarifying updates issued during 2016. This ASU was effective for the Company beginning February 1, 2018. The adoption of this ASU did not have a material impact on the Company's results of operations or financial position. Refer to Note 4 - Revenue recognition - for more detail. The Company evaluated other recent accounting pronouncements and does not expect them to have a material impact on its consolidated financial statements or related disclosures.
