Significant Accounting Policies [Text Block]	11. Summary of Significant Accounting Policies New Accounting Pronouncements In February 2018, the FASB issued ASU No. 2018 - 02, Income Statement-Reporting Comprehensive Income (Topic 220 ): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“AOCI”). The accounting standard allows for the optional reclassification of stranded tax effects within accumulated other comprehensive income to retained earnings that arise due to the enactment of the Tax Cuts and Jobs Act of 2017 (the “Tax Act”). The amount of the reclassification would reflect the effect of the change in the U.S. federal corporate income tax rate on the gross deferred tax amounts and related valuation allowances, if any, at the date of enactment of the Tax Act and other income tax effects of the Tax Act on items remaining in accumulated other comprehensive income. The standard will be effective for annual periods beginning after December 15, 2018, including interim periods within that reporting period with early adoption permitted. The Company is currently evaluating the impact of its pending adoption of the new standard on its consolidated financial statements. In January 2017, the FASB issued Accounting Standard Update 2017 - 04 (ASU 2017 - 04 ), Intangibles-Goodwill and Other (Topic 350 ) Simplifying the Test for Goodwill Impairment. With ASU 2017 - 04, an entity will no longer determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. Instead, if the carrying amount of a reporting unit exceeds its fair value an impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to the reporting unit. ASU 2017 - 04 is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The Company is currently evaluating the impact the adoption of ASU 2017 - 04 will have on our consolidated financial statements. In June 2016, the FASB issued ASU 2016 - 13 amending how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance requires the application of a current expected credit loss model which is a new impairment model based on expected losses. Under this model, an entity recognizes an allowance for expected credit losses based on historical experience, current conditions and forecasted information rather than the current methodology of delaying recognition of credit losses until it is probable a loss has been incurred. This ASU is effective for interim and annual reporting periods beginning after December 15, 2019 with early adoption permitted for annual reporting periods beginning after December 15, 2018. The Company is currently evaluating the impact of the new guidance on our consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU 2016 - 02 amending the existing accounting standards for lease accounting and requiring lessees to recognize a right of use asset and liability for all leases with lease terms of more than 12 months, including those classified as operating leases. Both the asset and liability will initially be measured at the present value of the future minimum lease payments, with the asset being subject to adjustments such as initial direct costs. Consistent with current GAAP, the presentation of expenses and cash flows will depend primarily on the classification of the lease as either a finance or an operating lease. The new standard also requires additional quantitative and qualitative disclosures regarding the amount, timing and uncertainty of cash flows arising from leases in order to provide additional information about the nature of an organization's leasing activities. This ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018 and requires modified retrospective application. Early adoption is permitted. The Company is currently evaluating the impact of the new guidance on our consolidated financial statements and related disclosures. Upon adoption, the Company expects the amount recognized for the right of use assets and liabilities to be material to the consolidated financial statements.
