Use of Estimates and Reclassifications Disclosure [Text Block]	2. USE OF ESTIMATES AND RECLASSIFICATIONS The Company’s reports for interim periods utilize numerous estimates of general and administrative expenses and other costs for the full year. Future actual amounts may differ from these estimates. Amounts reflected in interim reports are not necessarily indicative of results for a full year. Certain amounts in the December 31, 2018 condensed consolidated balance sheet were reclassified to conform to the current period’s presentation. Such amounts had no impact on net income and comprehensive income (loss) previously reported.
