Net Loss per Share

Note 10. Net Loss per Share

Basic loss per common share is computed by dividing the net loss allocable to common stockholders by the weighted-average number of shares of common stock or common stock equivalents outstanding. Diluted loss per common share is computed similar to basic loss per share except that it reflects the potential dilution that could occur if dilutive securities or other obligations to issue common stock were exercised or converted into common stock. Securities that could potentially dilute loss per share in the future that were not included in the computation of diluted loss per share at December 31, 2021 and 2020 are as follows:

	As of December 31,
	2021		2020
Convertible preferred stock		577		688
Warrants to purchase common stock		5,801,701		1,656,354
Options to purchase common stock		479,654		384,304
Total		6,281,932		2,041,346
