The restricted shares issued to Walmart contain non-forfeitable rights to dividends and are considered participating securities for purposes of computing EPS pursuant to the two-class method. The computation above excludes income attributable to the unvested restricted shares from the numerator and excludes the dilutive impact of those underlying shares from the denominator. The number of weighted average shares issued and outstanding in periods of net loss are the same for basic and diluted EPS, as the effects of including potentially dilutive common shares is anti-dilutive.

For the periods presented, we excluded certain restricted stock units and stock options outstanding (as applicable), which could potentially dilute basic EPS in the future, from the computation of diluted EPS as their effect was anti-dilutive. Additionally, we have excluded any performance-based restricted stock units where the performance contingency has not been met as of the end of the period. The following table shows the weighted-average number of shares excluded from the diluted EPS calculation as their effects were anti-dilutive:
