Net (Loss) Per Share
 
Basic (loss) per share (EPS) was computed by dividing net (loss) by the weighted average number of shares of common stock outstanding during the period. Diluted EPS differs from basic EPS due to the assumed conversion of potentially dilutive awards and options that were outstanding during the period. The following is a reconciliation of the numerators and the denominators of the basic and diluted per share computations for net (loss) for the 
three
months ended
March 31, 2021
and
March 31, 2020
.

The awards and options to purchase shares of common stock that were outstanding at
March 31, 2021
and
March 31, 2020
that were
not
included in the computation of diluted earnings per share because the effect would have been anti-dilutive, are as follows:
