EARNINGS PER SHARE (EPS) |
EARNINGS PER SHARE (''EPS'') | 3. EARNINGS PER SHARE (“EPS”): Basic EPS is determined using the weighted average number of common shares outstanding during the period. Diluted EPS is determined using the weighted average number of common shares and potential common shares (representing the dilutive effect of stock options, RSUs and ESPP shares) outstanding during the period using the treasury stock method. The following table presents the computation of basic and diluted net income (loss) per share attributable to Aehr Test Systems common shareholders (in thousands, except per share data):

For the purpose of computing diluted earnings per share, the weighted average number of potential common shares does not include stock options with an exercise price greater than the average fair value of the Company’s common stock for the period, as the effect would be anti-dilutive. Stock options to purchase 64,000 shares of common stock were outstanding as of May 31, 2022 but were not included in the computation of diluted net income per share, because the inclusion of such shares would be anti-dilutive. In the fiscal year ended May 31, 2021 and 2020, potential common shares have not been included in the calculation of diluted net loss per share as the effect would be anti-dilutive. As such, the numerator and the denominator used in computing both basic and diluted net loss per share for these periods are the same. Stock options to purchase 2,766,000 and 3,153,000 shares of common stock were outstanding on May 31, 2021 and 2020, respectively, but were not included in the computation of diluted net loss per share, because the inclusion of such shares would be anti-dilutive. ESPP rights to purchase 239,000 and 192,000 ESPP shares were outstanding on May 31, 2021 and 2020, respectively, but were not included in the computation of diluted net loss per share, because the inclusion of such shares would be anti-dilutive. RSUs for 132,000 shares and 10,000 shares were outstanding on May 31, 2021 and 2020, respectively, but were not included in the computation of diluted net loss per share, because the inclusion of such shares would be anti-dilutive.
