Note 10. 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 is due entirely to the assumed exercise of stock options and the vesting and settlement of RSUs.

Performance awards 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 the end of the related performance period and the result would be dilutive under the treasury stock method.

The Company’s performance awards outstanding at June 30, 2015 did not meet the related performance conditions and therefore were excluded from the calculation of diluted EPS. For the three-month periods ended June 30, 2015 and 2014, approximately 0.4 million and 0.3 million weighted-average shares, respectively, were excluded from the calculation of EPS because they were anti-dilutive. For each of the six-month periods ended June 30, 2015 and 2014, approximately 0.2 million weighted-average shares were excluded from the calculation of EPS because they were anti-dilutive.

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