Basic and Diluted Net Income (Loss) Per Common Share

5. Basic and Diluted Net Income (Loss) Per Common Share

Basic and diluted net income (loss) per common share is computed based on the weighted-average number of common shares outstanding. Common share equivalents (which consist of options, warrants and restricted stock) are excluded from the computation of diluted net income (loss) per common share where the effect would be anti-dilutive.  Common share equivalents that could potentially dilute net income (loss) per share in the future, and which were excluded from the computation of diluted income (loss) per share, totaled 9.2 million shares for the three-month period ended March 31, 2014, and 11.0 million for the three-month period ended March 31, 2013.
