9. Net Loss per Share

Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding. Diluted net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding including the effect of common share equivalents. Diluted net loss per share assumes the issuance of potential dilutive common shares outstanding for the period and adjusts for any changes in income and the repurchase of common shares that would have occurred from the assumed issuance, unless such effect is anti-dilutive. Net loss attributable to common stockholders for the three months ended March 31, 2023 was $4.5 million. Net loss attributable to common stockholders for the three months ended March 31, 2022 was $4.3 million. The number of options and warrants for the purchase of common stock that were excluded from the computations of net loss per common share and for the three months ended March 31, 2023 were 2,295,469 and 634,426, respectively and for the three months ended March 31, 2022 were 610,772 and 634,426, respectively, because their effect is anti-dilutive.
