LOSS PER SHARE

Basic loss per share is computed by dividing net loss by the weighted average number of shares outstanding. Diluted loss per share is computed by also considering the impact of potential common stock on both net loss and the weighted average number of shares outstanding. Our potential common stock consists of employee stock options, restricted stock units and performance-based awards. Our potential common stock is included in the diluted earnings per share calculation when adding such potential common stock would not be anti-dilutive. Performance-based awards are included in the computation of diluted earnings per share only to the extent that the underlying performance conditions (and any applicable market condition) (i) are satisfied as of the end of the reporting period or (ii) would be considered satisfied if the end of the reporting period were the end of the related contingency period and the result would be dilutive under the treasury stock method. When we report a net loss for the period presented, the calculation of diluted net loss per share excludes our potential common stock, as the effect would be anti-dilutive.

For the three months ended March 31, 2021, there were approximately 446,650 shares issuable upon the exercise of options and the contingent vesting of performance-based restricted stock units that were excluded from the dilutive calculations, as they were anti-dilutive. For the three months ended March 31, 2020, there were approximately 676,232 issuable upon the exercise of options that were excluded from the dilutive calculations, as they were anti-dilutive.

A reconciliation of the number of common shares used in the calculation of basic and diluted loss per share is presented below:
