Earnings Per Share [Abstract]

Earnings Per Share

Note 8. Earnings Per Share

Basic 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 of restricted stock and RSUs. The dilutive effect of stock options and RSUs excludes shares that would be anti-dilutive to the calculation of EPS if included. For the three-month period ended March 31, 2013, approximately 0.4 million anti-dilutive weighted-average shares have been excluded from the calculation of EPS. For the three-month period ended March 31, 2012, less than 0.1 million anti-dilutive weighted-average shares were excluded from the calculation of EPS. The dilutive effect of stock options, restricted stock, and RSU awards for each period reported is summarized below:
