Net Loss Per Share

Note 2—Net Loss Per Share

Basic net loss per share is calculated by dividing the net loss by the weighted-average number of common shares outstanding for the period. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common shares and dilutive common share equivalents outstanding for the period, determined using the treasury-stock method. Common share equivalents are excluded from the diluted net loss per share computation if their effect is anti-dilutive.

The basic and diluted net loss per share amounts for the three months ended March 31, 2020 and 2019 were computed based on the shares of common stock outstanding during the respective periods. Potentially dilutive securities excluded from the diluted loss per share calculation are as follows:

	March 31,
	2020	2019
Outstanding options to purchase common stock	12,591,341	11,840,521
Outstanding warrants to purchase common stock	243,115	243,115
Total potentially dilutive shares excluded from loss per share	12,834,456	12,083,636
