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.

In determining the potential dilution effect of outstanding stock options during the three and nine months ended September 30, 2018, the Company used the quarterly and nine-month ended average common stock close price of $19.91 and $18.06 per share, respectively. The Company reported a net loss for the three and nine months ended September 30, 2018.

In determining the potential dilution effect of outstanding stock options during the three and nine months ended September 30, 2017, the Company used the quarterly and nine-month ended average common stock close price of $15.39 and $17.02 per share, respectively. For the three and nine months ended September 30, 2017, approximately 0.2 million and 0.5 million shares of the Company's common stock subject to options were excluded from the diluted EPS calculation, respectively, as the effect would have been antidilutive.
