Due to the net loss for the
three
and
six
months ended
June 
30,
2019
and
2018,
the computation of dilutive weighted-average common shares outstanding does
not
include any stock options or any shares of unvested restricted common stock as these potential awards are anti-dilutive.
 
Because the effect would be anti-dilutive, there were
1,121,332
stock options outstanding that were
not
included in the computation of diluted weighted-average shares outstanding for each of the
three
and
six
months ended
June 
30,
2019
and
2018.
