[1] The Company had net losses from continuing operations for all periods presented. Therefore, the effect of common share equivalents of 982 and 165 for the three months ended September 30, 2012 and 2011, respectively, and 1,017 and 305 for the nine months ended September 30, 2012 and 2011, respectively, are excluded from the calculation of diluted loss per share for these periods because they would be antidilutive.
