Earnings Per Share [Text Block] | (8) Net Loss per Share Basic net loss per share is computed based on the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share is computed based on the weighted average number of common shares outstanding plus the effect of potentially dilutive common shares outstanding during the period using the treasury stock method and the if-converted method. Potentially dilutive common shares include outstanding stock options and share-based awards. The following table reconciles the numerators and denominators used in the computations of both basic and diluted net loss per share:
|  | Three Months Ended |
|  | September 30, |
(In thousands, except per share data) |  | 2025 |  |  | 2024 |
Numerator: |  |  |  |  |  |  |  |
Net loss |  | $ | (3,465 | ) |  | $ | (3,278 | )
Denominator: |  |  |  |  |  |  |  |
Denominator for basic and diluted net loss per share — weighted average common stock outstanding |  |  | 1,673 |  |  |  | 1,631 |
Basic and diluted net loss per common share: |  |  |  |  |  |  |  |
Net loss per common share |  | $ | (2.07 | ) |  | $ | (2.01 | )
All unvested restricted stock awards and convertible Series D preferred shares for the three months ended September 30, 2025, are not included in diluted net loss per share, as the impact to net loss per share would be anti-dilutive. Options to purchase 275,462 shares of common stock at exercise prices ranging from $4.73 to $175.50 per share outstanding as of September 30, 2025, were not included in diluted net loss per share, as the impact to net loss per share would be anti-dilutive.
