Earnings Per Share [Abstract]  
Net Income per Share
7.Earnings Per Share
Basic EPS is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted EPS is computed by dividing net income by the weighted average number of common shares outstanding during the period, plus the dilutive effect of time-vested and performance-based restricted stock units (“RSUs”).
The following table summarizes the net income and the basic and diluted shares used in the earnings per share computations:
