Income (Loss) Per Common Share

(3) Income (Loss) Per Common Share

Basic income (loss) per common share is the amount of income (loss) for the period divided by the weighted average shares of common stock outstanding during the reporting period. Diluted income (loss) per common share is the amount of income (loss) for the period plus interest expense on convertible debt divided by the sum of weighted average shares of common stock outstanding during the reporting period and weighted average shares that would have been outstanding assuming the issuance of common shares for all dilutive potential common shares.

Potential common shares of approximately 7.2 million, 8.0 million and 8.3 million during the years ended December 31, 2013, 2012, and 2011, respectively, that could potentially dilute basic income (loss) per common share in the future were not included in the computation of diluted income (loss) per share because to do so would have been anti-dilutive for the periods presented. Potential dilutive common shares for the years ended December 31, 2013, 2012 and 2011 include approximately 3.0 million, 3.0 million and 4.7 million common shares related to convertible debentures, respectively, and 4.1 million, 5.0 million, and 3.6 million shares, respectively, related to stock options, restricted stock, and restricted stock units.
