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 for which 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:
| Three Months Ended September 30, |  | Nine Months Ended September 30,
