Earnings Per Share [Abstract]

Earnings Per Share

6. Earnings (Loss) Per Share

Basic earnings(loss) per share is computed by dividing net income(loss) applicable to common stockholders by the weighted average numbers of shares of common stock outstanding during the period. Diluted earnings(loss) per share is computed similarly to basic earnings(loss) per share, except that the denominator is increased for the assumed exercise of dilutive stock options and unvested restricted stock calculated using the treasury stock method.
