Earnings Per Share [Abstract]  
9. Basic and Diluted Earnings per Common Share

Basic earnings per share excludes the dilutive effects of options, warrants and other convertible securities. Diluted earnings per share reflects the potential dilutions of securities that could share in the Company’s earnings. Options, warrants, convertible preferred stock and deferred stock units representing approximately 9,607,000 and 7,030,000 shares were excluded from the computations of diluted net loss per common share for the years ended December 31, 2013 and 2012, respectively, as their effect was anti-dilutive.
