Earnings Per Share [Abstract] |
EARNINGS (LOSS) PER COMMON SHARE | EARNINGS (LOSS) PER COMMON SHARE Basic earnings (loss) per share is computed using the weighted-average number of common shares outstanding for the period. Diluted earnings (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. Potentially dilutive shares are excluded from the computation of diluted earnings (loss) per share if their effect is anti-dilutive. There were no options outstanding at December 31, 2020. Options to purchase 60,000 shares of common stock were excluded from the computation of diluted shares for the three months ended December 31, 2019, as their inclusion would have been anti-dilutive. Reconciliations between net earnings (loss) attributable to Barnwell stockholders and common shares outstanding of the basic and diluted net earnings (loss) per share computations are detailed in the following tables:
