Income Tax Disclosure [Text Block]	NOTE 4 – INCOME T AXES As of March 31, 2020, the Company had net operating loss (“NOL”) carryforwards of approximately $329 million for federal income tax purposes and $220 million for California state income tax purposes. Such carryforwards expire in varying amounts through the year 2040. For federal losses arising in tax years ending after December 31, 2017, the NOL carryforwards are allowed indefinitely. Use of the carryforward amounts is subject to an annual limitation as a result of ownership changes. As of March 31, 2020, the Company possessed unrecognized tax benefits totaling approximately $1.5 million. None of these, if recognized, would affect the Company's effective tax rate because the Company has recorded a full valuation allowance against these assets. Because it is more likely than not that the Company will not realize its net deferred tax assets, it has recorded a full valuation allowance against these assets. Accordingly, no deferred tax asset has been reflected in the accompanying condensed consolidated balance sheet.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
