Significant Accounting Policies [Text Block]	12. Summary of Significant Accounting Policies New Accounting Pronouncements 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, an entity will compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value. 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 January 2017, the FASB issued ASU 2017 - 01, Clarifying the Definition of a Business, which clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. ASU 2017 - 01 is required to be applied prospectively for reporting periods beginning after December 31, 2017. The impact on the Company's consolidated financial statements will depend on the facts and circumstances of any specific future transactions. In March 2016, the FASB issued ASU No. 2016 - 09, “Compensation— Stock Compensation (Topic 718)” (“ASU 2016 - 09”). The guidance changes how companies account for certain aspects of equity-based payments to employees. Entities will be required to recognize income tax effects of awards in the income statement when the awards vest or are settled. The guidance also allows an employer to repurchase more of an employee’s shares than it can under current guidance for tax withholding purposes providing for withholding at the employee’s maximum rate as opposed to the minimum rate without triggering liability accounting and to make a policy election to account for forfeitures as they occur. The updated guidance is effective for annual periods beginning after December 15, 2016. Effective January 1, 2017, the Company adopted the accounting guidance contained within ASU 2016 - 09. In February 2016, the FASB issued ASU 2016 - 02 amending the existing accounting standards for lease accounting and requiring lessees to recognize lease assets and lease liabilities 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 U.S. Generally Accepted Accounting Principles ("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. We are currently evaluating the impact of the new guidance on our consolidated financial statements and related disclosures. As our operations are conducted in leased facilities, this ASU may require us to disclose additional information about our leasing activities. We plan to evaluate the impact of the new guidance on our consolidated financial statements and related disclosures. In November 2015, the FASB issued ASU 2015 - 17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes, simplifying the balance sheet classification of deferred taxes by requiring all deferred taxes, along with any related valuation allowance, to be presented as noncurrent. This ASU is effective for the Company beginning in the first quarter of 2017, which the Company has applied retrospectively. Upon the adoption of the guidance, the Company reclassified $471,000 from current assets to non-current assets, and reduced both non-current assets and current liabilities by $2,389,000. In May 2014, the FASB issued new revenue recognition guidance under ASU 2014 - 09 that will supersede the existing revenue recognition guidance under U.S. GAAP. The new standard focuses on creating a single source of revenue guidance for revenue arising from contracts with customers for all industries. The objective of the new standard is for companies to recognize revenue when it transfers the promised goods or services to its customers at an amount that represents what the company expects to be entitled to in exchange for those goods or services. In July 2015, the FASB deferred the effective date by one year (ASU 2015 - 14). This ASU will now be effective for annual periods, and interim periods within those annual periods, beginning on or after December 15, 2017. Early adoption is permitted, but not before the original effective date of December 15, 2016. Since the issuance of the original standard, the FASB has issued several other subsequent updates including the following: 1) clarification of the implementation guidance on principal versus agent considerations (ASU 2016 - 08); 2) further guidance on identifying performance obligations in a contract as well as clarifications on the licensing implementation guidance (ASU 2016 - 10); 3) rescission of several SEC Staff Announcements that are codified in Topic 605 (ASU 2016 - 11); 4) additional guidance and practical expedients in response to identified implementation issues (ASU 2016 - 12); and 5) technical corrections and improvements (ASU 2016 - 20). The company is currently assessing the method under which it will adopt and the potential impact of adopting ASU 2014 - 09 on its financial position, results of operations, cash flow and/or disclosures.
