Earnings Per Share [Abstract]  
Earnings (Loss) Per Share
(5)Earnings (Loss) Per Share. Basic earnings (loss) per share has been computed on the basis of the weighted-average number of shares of common stock outstanding during the period. For 2013  basic and diluted loss per share is the same due to the net loss incurred by the Company. For 2014 basic and diluted earnings per share are the same because stock options outstanding during the period were not dilutive due to their exercise prices exceeding the fair value of the Company’s common stock during the period. Loss per common share has been restated for all periods presented to reflect the one-for-four reverse common share split effective May 31, 2013. Earnings (loss) per common share have been computed based on the following:
