Earnings Per Share [Abstract] |
Earnings Per Share & Diluted Earnings Per Share | 4. Earnings Per Share & Diluted Earnings Per Share Basic EPS is computed by dividing net income (loss) available to common shareholders 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 EPS is calculated in the same manner as basic EPS. For the years 2022, 2021 and 2020, options for 189,000, 101,000 and 642,000 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 denominators of the basic and diluted EPS calculations follows, in thousands, except per share amounts:
