Share-Based Payment Arrangement [Text Block] | Note 8 - Stock-based compensation The Company has prior incentive plans under which previously granted awards remain outstanding, but under which no new awards may be granted, including the Company's 2021 Omnibus Stock Incentive Plan, which expired in May 2024. At July 31, 2024, the Company had reserved a total 196,026 shares for grants and issuances under these incentive plans, including issuances pursuant to unvested or unexercised prior awards. The Company's prior incentive plans 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 prior incentive plans authorized awards to officers, employees, consultants, and independent directors. The Company's 2024 Omnibus Stock Incentive Plan, dated May 28, 2024, was approved by the Company's stockholders in July 2024 ("2024 Plan"). The 2024 Plan will expire in July 2027. The 2024 Plan authorizes awards to officers, employees, consultants, and independent directors. Grants were made in connection with the 2024 Plan and the prior incentive plans to employees, officers, and independent directors, as further described below.
