Income Tax Disclosure [Text Block]	9. Income Taxes The Company accounts for income taxes under ASC Topic 740 – Income Taxes. Under this standard, deferred tax assets and liabilities are recognized for future tax benefits or consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled We have recorded a full valuation allowance against our deferred tax assets. As we continue to have multiple quarters of positive net income, we will assess our valuation allowance. Based on all available evidence, we determined that we have not yet attained a sustained level of profitability. Therefore, we have maintained the full valuation allowance as of March 31, 2020. We may release all, or a portion, of the valuation allowance in the near-term, dependent on the verifiable positive evidence observed in future quarters.
