EARNINGS PER SHARE ("EPS")

The computations of basic EPS are based on our weighted average shares outstanding. The basic weighted average number of shares of Common Stock outstanding was 14,598,000, 14,597,000 and 23,021,000 for the years ended December 31, 2019, 2018 and 2017, respectively. In order to calculate the diluted weighted average number of shares of Common Stock outstanding for the years ended December 31, 2019 and 2017, the basic weighted average number of shares of Common Stock outstanding was increased by 1,895,000 and 2,000, respectively, to reflect the dilutive effect of certain shares of our Series A Preferred Stock. The computation of diluted EPS does not include outstanding shares of Series A Preferred Stock for the year ended December 31, 2018 because their impact was deemed to be anti-dilutive. Outstanding Series A Preferred Warrants were not included in the computation of diluted EPS for the years ended December 31, 2019, 2018 and 2017 because their impact was either anti-dilutive or such warrants were not exercisable during such periods (Note 11). Outstanding shares of Series L Preferred Stock were not included in the computation of diluted EPS for the years ended December 31, 2019, 2018 and 2017 because such shares were not redeemable during such periods.

EPS for the year-to-date period may differ from the sum of quarterly EPS amounts due to the required method for computing EPS in the respective periods. In addition, EPS is calculated independently for each component and may not be additive due to rounding.

The following table reconciles the numerator and denominator used in computing our basic and diluted per-share amounts for net income (loss) attributable to common stockholders for the years ended December 31, 2019, 2018 and 2017:
