Earnings Per Share [Abstract]

EARNINGS PER SHARE

3. EARNINGS PER SHARE

Basic earnings per share is calculated by dividing income available to stockholders by the weighted-average number of common shares outstanding during each period. Diluted earnings per share is computed using the weighted-average number of common and dilutive common share equivalents outstanding during the period. Dilutive common share equivalents consist of shares issuable upon the exercise or settlement of stock awards (calculated using the treasury stock method) during the period they were outstanding.

The following table sets forth the computation of basic and diluted net income per share (in thousands, except per share information):
