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 restricted stock units ("RSUs"). The dilutive effect of stock options excludes shares that would be anti-dilutive to the calculation of EPS if included. The dilutive effect of stock options, restricted stock, and RSU awards for each period reported is summarized below:
