Note 5 - Earnings Per Share ("EPS")

Basic EPS is computed by dividing net income (loss) by the basic weighted-average number of shares outstanding during the period.

Diluted EPS is computed by dividing net income by the diluted weighted-average number of shares outstanding during the period and, accordingly, reflects the potential dilution that could occur if securities or other agreements to issue common stock, such as stock options, were exercised, settled or converted into common stock and were dilutive. The diluted weighted-average number of shares used in our diluted EPS calculation is determined using the treasury stock method. For periods in which we recognize losses, the calculation of diluted loss per share is the same as the calculation of basic loss per share.

Unvested awards of share-based payments with rights to receive dividends or dividend equivalents, such as our restricted stock awards, are considered to be participating securities, and therefore, the two-class method is used for purposes of calculating EPS. Under the two-class method, a portion of net income is allocated to these participating securities and is excluded from the calculation of EPS allocated to common stock. Our restricted stock awards are subject to forfeiture and restrictions on transfer until vested and have identical voting, income and distribution rights to the unrestricted common shares outstanding.

Our weighted average unvested restricted stock awards outstanding were 114,282 and 364,056 for the three months ended September 30, 2020 and 2019, respectively, and 146,109 and 493,495 for the nine months ended September 30, 2020 and 2019, respectively.

The calculations of basic and diluted EPS are as follows:
