4. Net Loss per Share

Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potential shares of common stock, including stock options and restricted stock units, to the extent dilutive. Basic and diluted net loss per share were the same for the three months ended March 31, 2019 and 2018, as the inclusion of all potential common shares outstanding would have been anti-dilutive.
