Earnings Per Share [Abstract] |
LOSS PER COMMON SHARE | LOSS PER COMMON SHARE Basic loss per share is computed using the weighted-average number of common shares outstanding for the period. Diluted loss per share is calculated using the treasury stock method to reflect the assumed issuance of common shares for all potentially dilutive securities, which consist of outstanding stock options and nonvested restricted stock units. Potentially dilutive shares are excluded from the computation of diluted loss per share if their effect is anti-dilutive. Options to purchase 465,000 shares of common stock and 98,795 restricted stock units were excluded from the computation of diluted shares for the year ended September 30, 2024, as their inclusion would have been anti-dilutive. Options to purchase 546,781 shares of common stock and 18,605 restricted stock units were excluded from the computation of diluted shares for the year ended September 30, 2023, as their inclusion would have been anti-dilutive. Reconciliations between net loss attributable to Barnwell stockholders and common shares outstanding of the basic and diluted net loss per share computations are detailed in the following tables:
