Significant Accounting Policies [Text Block]	12. Summary of Significant Accounting Policies New Accounting Pronouncements In March 2018, the FASB issued ASU 2018 - 05, Income Taxes , to clarify the accounting implications of Staff Accounting Bulletin No. 118 ("SAB 118" ). SAB 118 provides a measurement period that should not extend beyond one year from December 22, 2017, the date of the enactment of the Tax Cuts and Jobs Act, to complete the accounting under Accounting Standards Codification ("ASC") 740, Income Taxes . As of September 30, 2018, we have not adjusted the provisional estimate recorded at December 31, 2017. We expect to complete our analysis within the measurement period in accordance with SAB 118. In February 2018, the FASB issued ASU 2018 - 02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income , which amends existing guidance for reporting comprehensive income to reflect changes resulting from the Tax Cuts and Jobs Act of 2017. The amendment provides the option to reclassify stranded tax effects within accumulated other comprehensive income (AOCI) to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the Act is recorded. New disclosures will be required upon adoption, including the accounting policy for releasing income tax effects from AOCI, whether reclassification of stranded income tax effects is elected, and information about other income tax effect reclassifications. Although the amendment will become effective for us on January 1, 2019, early adoption is permitted, although we do not plan to early adopt. We are currently evaluating the impact of adopting this standard on our consolidated financial statements and disclosures. 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. On January 1, 2018, the Company prospectively adopted ASU 2017 - 01, Business Combinations: Clarifying the Definition of a Business , to clarify the definition of a business to assist entities when evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The impact of the adoption did not have an impact on its results of operations, financial position or cash flows. 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 No. 2016 - 02, "Leases (Topic 842 )". Under Topic 842, an entity will be required to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. Topic 842 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. For public companies, Topic 842 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, and requires a modified retrospective adoption, with early adoption permitted. In July 2018, the FASB issued ASU 2018 - 10, "Codification Improvements to Topic 842, Leases". This ASU makes various targeted amendments to the leasing standard and we are evaluating this ASU in connection with adoption of the standard. In July 2018, the FASB issued ASU 2018 - 11, "Leases (Topic 842 ): Targeted Improvements." This standard allows entities to initially apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The Company will adopt the standard on January 1, 2019 and is still evaluating the adoption method that will be used. The standard also provides for certain practical expedients. The Company continues to evaluate and is in the process of documenting the impact of the pending adoption of the new standard on its consolidated financial position and/or, disclosures and/or internal controls process. The Company believes the adoption of Topic 842 will result in the Company recording right-of-use assets and liabilities on the consolidated balance sheets for leases currently classified as operating leases, along with enhanced disclosures of lease activity.
