Net Loss Per Share

6 Months Ended

Jun. 30, 2019

Net loss per share is computed by dividing the net loss by the weighted average number of shares of common stock outstanding. Outstanding stock options, restricted stock units and warrants have not been included in the calculation of diluted net loss per share because to do so would be anti-dilutive. Accordingly, the numerator and the denominator used in computing both basic and diluted net loss per share for each period are the same.

The following shares underlying outstanding options, restricted stock units and warrants were excluded from the computation of basic and diluted net loss per share for the periods presented (in thousands):
