Basic net loss per share is computed by dividing the net loss in each period by the weighted-average number of common shares outstanding during such period. Diluted net loss per share is computed similarly to basic net loss per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential common shares had been issued and if the additional common shares were dilutive. For the periods presented, common stock equivalents, consisting of stock-based awards and the SWK Warrant, were not included in the calculation of the diluted loss per share because to do so would be anti-dilutive. The SWK Warrant price is subject to a proportionate adjustment in the event of a stock dividend or stock split. The Company concluded that they should be deemed participating securities. However, as the Company is currently operating in a net loss position as of Q1 2022 and has not declared any dividends, such inclusion of the participating securities related to the SWK Warrant (as common stock equivalents) would be anti-dilutive and thus would be excluded from the calculation of net loss per share. As of March 31, 2022, the Company excluded from its net loss per share calculations 2.4 million shares related to the Secured Convertible Notes under the “if-converted” method, since even after adjusting for discrete items related to the Secured Convertible Notes for interest and adjustment of fair value, the Company has a net loss during the period and to include these shares would be anti-dilutive.

As of March 31, 2022 and 2021, the number of shares of common stock underlying potentially dilutive securities consist of:

	March 31,
	2022		2021
Options to purchase common stock		2,796,100		1,706,475
SWK Warrant		150,000		—
Total		2,946,100		1,706,475
