5. Loss per share

The net loss per share is calculated by dividing the net loss attributable to common stockholders by the weighted average number of shares outstanding for the years ended December 31, 2022, and 2021. In accordance with ASC Topic 260-10-45-13, Earnings Per Share, the weighted average of number of shares outstanding includes outstanding common stock and shares issuable for nominal consideration. Accordingly, warrants issued with a $0.01 per share exercise price, are included in weighted average shares outstanding as follows:

(in thousands)	December 31, 2022		December 31, 2021
Common shares		526,530		481,620
Common shares issuable assuming exercise of nominally priced warrants		22,941		36,736
Weighted Average Shares Outstanding		549,471		518,356

Diluted net loss per share would be computed by dividing the net loss attributable to common stockholders by the weighted average number of shares of common stock and dilutive common stock equivalents outstanding. To the extent that securities are “anti-dilutive,” they are excluded from the calculation of diluted net loss per share. As a result of the net loss for the years ended December 31, 2022, and 2021, all potentially dilutive shares were anti-dilutive and therefore excluded from the computation of diluted net loss per share. Anti-dilutive equity securities consist of the following:

(in thousands)	December 31, 2022		December 31, 2021
Common stock options		21,246		31,760
Common stock purchase warrants		1,186,522		168,192
Convertible notes payable, including interest		603,425		90,380
		1,811,193		290,332
