Earnings (Loss) Per Share [Abstract]

Earnings (Loss) Per Share

11.  Earnings (Loss) Per Share

Earnings or loss per share is calculated by dividing the net income or loss for the period by the weighted average number of shares of common stock outstanding during the period. Diluted earnings or loss per share (“Diluted EPS”) is calculated by dividing the net income or loss for the period by the total of the weighted average number of shares of common stock outstanding during the period plus the effects of any dilutive securities. Diluted EPS considers the impact of potentially dilutive securities except in periods in which there is a loss because the inclusion of the potential shares of common stock would have an anti-dilutive effect. During all periods presented in the Company’s Condensed Consolidated Statements of Operations, potentially dilutive securities included shares of common stock potentially issuable upon exercise of stock options. Diluted EPS excludes the impact of potential issuance of shares of common stock related to the Company’s stock options in periods in which the exercise price of the stock option is greater than the average market price of the Company’s common stock during such periods.

For the six-month periods ended June 30, 2011 and 2010, 8,387,333 and 7,977,346 shares of common stock equivalents, respectively, were excluded from the computation of dilutive loss per share since their effect would be antidilutive. For the three-month periods ended June 30, 2011 and 2010, 8,387,333 and 7,977,346 shares of common stock equivalents, respectively, were excluded from the computation of dilutive loss per share since their effect would be antidilutive.
