Share-Based Payment Arrangement [Text Block] | Note 7 - Stock-based compensation The Company's 2021 Omnibus Stock Incentive Plan dated May 26, 2021 was approved by the Company's stockholders in May 2021 ("2021 Plan"). The 2021 Plan will expire in May 2024. The 2021 Plan authorizes awards to officers, employees, consultants and independent directors. Grants were made to the Company's employees, officers and independent directors under the 2021 Plan, as described below. The Company’s 2017 Omnibus Stock Incentive Plan dated June 13, 2017, as amended, which the Company's stockholders approved in June 2017 ("2017 Plan"), expired in June 2020. While the 2017 Plan provided for the grant of deferred shares, non-qualified stock options, incentive stock options, restricted shares, restricted stock units, and performance-based restricted stock units intended to qualify under section 422 of the Internal Revenue Code, the Company issued only restricted shares and restricted stock units under the 2017 Plan. The 2017 Plan authorized awards to officers, employees, consultants and independent directors. The Company has prior incentive plans under which previously granted awards remain outstanding, including the 2017 Plan, but under which no new awards may be granted. At July 31, 2022 the Company had reserved a total of 293,075 shares for grants and issuances under these incentive stock plans, which includes a reserve for issuances pursuant to unvested or unexercised prior awards.
