(3) Earnings Per Share

Basic earnings per share (EPS) is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted EPS reflects the potential dilution of common stock equivalent shares that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.

Our dilutive common stock equivalent shares consist of restricted stock units and stock options to purchase shares of common stock computed under the treasury stock method, using the average market price during the period. The following table presents instruments which were not dilutive and were excluded from the computation of diluted EPS in each period, as well as the dilutive common stock equivalent shares which were included in the computation of diluted EPS:
