Earnings Per Share [Abstract] |
Earnings Per Share | 4. Earnings Per Share Basic earnings per share (“EPS”) is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted EPS is computed similarly to basic EPS except that the denominator is increased to include the number of additional common shares that would have been outstanding if potentially dilutive common shares had been issued. In the case of a net loss, diluted earnings per share is calculated in the same manner as basic EPS. For the three and six months ended March 31, 2022, options for 187,000 and 95,000 weighted average shares, respectively, were excluded from the diluted EPS calculations because they were anti-dilutive. For the three and six months ended March 31, 2021, options for 98,000 and 349,000 weighted average shares, respectively, were excluded from the diluted EPS calculations because they were anti-dilutive. These shares could become dilutive in the future. A reconciliation of the components of the basic and diluted EPS calculations follows (in thousands, except per share amounts):
