Earnings Per Share [Text Block] | (12) Net Loss per Share Basic loss per share is computed on the basis of the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share is computed on the basis of the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method and the if-converted method. Dilutive potential common shares include outstanding stock options and stock-based awards. Reconciliation and the components of basic and diluted net loss per share are as follows (in thousands, except per share data):
|  | Year Ended June 30, |
|  | 2022 |  |  | 2021 |
Numerator: |  |  |  |  |  |  |  |
Net loss |  | $ | (8,330 | ) |  | $ | (7,603 | )
Denominator: |  |  |  |  |  |  |  |
Denominator for basic and diluted net loss per share — weighted average common stock outstanding |  |  | 47,702 |  |  |  | 21,984 |
Basic and diluted net loss per common share: |  |  |  |  |  |  |  |
Net loss |  | $ | (0.17 | ) |  | $ | (0.35 | )
All unvested restricted stock awards for the years ended June 30, 2022 and 2021 are not included in diluted net loss per share, as the impact to net loss per share is anti-dilutive. Options to purchase 1,028,532 shares of common stock at exercise prices ranging from $0.64 to $6.00 per share outstanding for the year ended June 30, 2022 and options to purchase 275,503 shares of common stock at exercise prices ranging from $1.85 to $7.50 per share outstanding for the year ended June 30, 2021 were not included in diluted net loss per share, as the impact to net loss per share is anti-dilutive.
