Earnings Per Share [Abstract]  
NET LOSS PER SHARE NET LOSS PER SHARENet loss per common share is computed using the two-class method, which is required due to the participating nature of the Preferred Stock (as defined and discussed in Note 6). Except with respect to voting and conversion rights, the rights of the holders of the Company’s common stock and the Preferred Stock are identical. Each class of shares has the same rights to dividends. Although the Preferred Stock are participating securities, such securities do not participate in net losses, and therefore, do not impact the Company’s net loss per share calculation as of June 30, 2022.
The Company computes basic net loss per share using the weighted-average number of common shares outstanding during the period. Diluted net loss per share is calculated by dividing net loss attributable to common stockholders by the weighted-average number of common shares plus potential common shares. The Company's stock options, including those with performance conditions, are included in the calculation of diluted net loss per share using the treasury stock method when their effect is dilutive. Potential common shares are excluded from the calculation of diluted net loss per share when their effect is anti-dilutive.

The following common stock equivalents were not included in the calculation of net loss per diluted share because their effect were anti-dilutive (in thousands):
