Earnings per share (“EPS”) is computed by dividing reported net income by the weighted-average number of shares outstanding. Diluted EPS considers the potential dilution that could occur if common stock equivalents were exercised or converted into stock. The difference between the basic and diluted weighted-average equivalent shares with respect to the Company’s EPS calculation was due entirely to the assumed exercise of stock options and the vesting and settlement of RSUs and PSAs. PSAs are included in the computation of diluted shares only to the extent that the underlying performance conditions (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 also the end of the applicable performance period and the result would be dilutive under the treasury stock method.

As of March 31, 2020, the PSAs granted during the year ended December 31, 2018 met the related performance conditions for the initial performance period and were included in the calculation of diluted EPS. However, the PSAs granted during the year ended December 31, 2019 and during the three months ended March 31, 2020 have not yet completed their initial two-year performance period and therefore were excluded in the calculation of diluted EPS. There were no weighted-average shares excluded from the calculation of EPS because they were anti-dilutive for the three months ended March 31, 2020 and 31,840 weighted-average shares were excluded for the three months ended March 31, 2019. The anti-dilutive shares were associated with RSUs.

The dilutive effect of stock options, RSUs, and PSAs for each period reported is summarized below:
