Subsequent Events [Text Block]	15. Other Items On January 25, 2022, the Company announced that its Board of Directors had launched a formal review process to explore strategic alternatives. The purpose of the review was to ensure that value was being maximized for shareholders, and that the Company has sufficient scale and financial resources to take advantage of potential growth opportunities available. These alternatives could include, among others, an outright sale of the Company, possible joint ventures, strategic partnerships or alliances, or other possible transactions. On June 14, 2022, the Company announced that it had completed the formal review process of exploring strategic alternatives and concluded that there were no opportunities presented to the Company that the Board of Directors believed would be in the best interests of the Company or its stockholders. While the active efforts will be suspended, the Company will continue to explore opportunities to grow the Company’s core businesses and will consider any opportunities that would be in the best interests of the Company and its stockholders.
