Income Tax Disclosure [Text Block] | NOTE 10 — INCOME TAXES Effective tax rates differ from federal statutory income tax rates primarily due to changes in the Company’s valuation allowance, permanent differences and provisions for state and local income taxes. As of June 30, 2021, the Company has a full valuation allowance recorded against deferred tax assets. During the six months ended June 30, 2021, the Company recorded a provision for income taxes of $77, compared to a provision for income taxes of $83 during the six months ended June 30, 2020. The Company files income tax returns in U.S. federal and state jurisdictions. As of June 30, 2021, open tax years in federal and some state jurisdictions date back to 1996 due to the taxing authorities’ ability to adjust operating loss carryforwards. As of December 31, 2020, the Company had federal and unapportioned state net operating loss (“NOL”) carryforwards of $260,598 of which $227,781 will generally begin to expire in 2026. The majority of the NOL carryforwards will expire in various years from 2028 through 2037. NOLs generated after January 1, 2018 will not expire. Since the Company has no unrecognized tax benefits, they will not have an impact on the condensed consolidated financial statements as a result of the expiration of the applicable statues of limitations within the next twelve months. In addition, Section 382 of the Internal Revenue Code of 1986, as amended (the “IRC”), generally imposes an annual limitation on the amount of NOL carryforwards and associated built-in losses that may be used to offset taxable income when a corporation has undergone certain changes in stock ownership. The Company’s ability to utilize NOL carryforwards and built-in losses may be limited, under IRC Section 382 or otherwise, by the Company’s issuance of common stock or by other changes in stock ownership. Upon completion of the Company’s analysis of IRC Section 382 in 2010, the Company determined that aggregate changes in stock ownership have triggered an annual limitation on NOL carryforwards and built-in losses available for utilization, thereby currently limiting annual NOL usage to $14,284 per year. Further limitations may occur, depending on additional future changes in stock ownership. To the extent the Company’s use of NOL carryforwards and associated built-in losses is significantly limited in the future, the Company’s income could be subject to U.S. corporate income tax earlier than it would be if the Company were able to use NOL carryforwards and built-in losses without such limitation, which could result in lower profits and the loss of benefits from these attributes. In February 2013, the Company adopted a Stockholder Rights Plan, which was amended and extended in February 2016 and again in February 2019 (as amended, the “Rights Plan”). The Rights Plan is designed to preserve the Company’s substantial tax assets associated with NOL carryforwards under IRC Section 382. The amendment to the Rights Plan was most recently approved by the Company’s stockholders at the Company’s 2019 Annual Meeting of Stockholders and has a term of three years. The Rights Plan is intended to act as a deterrent to any person or group, together with its affiliates and associates, becoming the beneficial owner of 4.9% or more of the Company’s common stock and thereby triggering a further limitation of the Company’s available NOL carryforwards. In connection with the adoption of the Rights Plan, the Board declared a non-taxable dividend of one preferred share purchase right (a “Right”) for each outstanding share of the Company’s common stock to the Company’s stockholders of record as of the close of business on February 22, 2013. Each Right entitles its holder to purchase from the Company one one-thousandth of a share of the Company’s Series A Junior Participating Preferred Stock at an exercise price of $4.25 per Right, subject to adjustment. As a result of the Rights Plan, any person or group that acquires beneficial ownership of 4.9% or more of the Company’s common stock without the approval of the Board would be subject to significant dilution in the ownership interest of that person or group. Stockholders who owned 4.9% or more of the outstanding shares of the Company’s common stock as of February 12, 2013 will not trigger the preferred share purchase rights unless they acquire additional shares after that date. As of June 30, 2021, the Company had no unrecognized tax benefits. The Company recognizes interest and penalties related to uncertain tax positions as income tax expense. The Company had no accrued interest and penalties as of June 30, 2021.
