Earnings Per Share [Abstract]

EARNINGS (LOSS) PER SHARE

EARNINGS (LOSS) PER SHARE

The Company calculates basic Earnings per Share ("EPS") by dividing net income (loss) by the weighted-average number of common shares outstanding for the period. Diluted EPS also reflects the potential dilution that could occur if common stock were issued for awards outstanding under the Mannatech, Incorporated 2017 Stock Incentive Plan (as defined below).

In determining the potential dilutive effect of outstanding stock options for each of the three months ended March 31, 2019, and 2018, the Company used the quarterly average common stock close price of $18.97 and $14.68 per share, respectively. For the three months ended March 31, 2019, approximately 0.1 million shares of the Company's common stock subject to options were excluded from the diluted EPS calculation, as the effect would have been antidilutive.
