Earnings Per Share [Abstract]

Earnings Per Share

3. Earnings Per Share

Basic earnings per share are calculated as net income divided by the weighted-average number of shares of common stock and restricted stock outstanding during the period. Diluted earnings per share assumes issuance of the net incremental shares from stock options when dilutive. The weighted-average common shares outstanding used to calculate diluted earnings per share reflect the dilutive effect of common stock equivalents including options to purchase shares of common stock, using the treasury stock method.

Basic and diluted weighted-average common shares outstanding and earnings per share include the following (in thousands, except per share data):
