EARNINGS (LOSS) PER COMMON SHARE
EARNINGS (LOSS) PER COMMON SHARE
 
The following table is a reconciliation of the numerators and denominators of our basic and diluted earnings (loss) per common share calculations for our continuing operations for three months ended March 31, 2018 and 2017. Net income available (loss attributable) to our common shareholders is expressed in millions and weighted average shares are expressed in thousands.

All potentially dilutive securities were excluded from the calculation of diluted loss per share for the three months ended March 31, 2017 because we did not report income from continuing operations available to common shareholders in that period. In circumstances where we do not have income from continuing operations available to common shareholders, the effect of stock options and other potentially dilutive securities is anti-dilutive, that is, a loss from continuing operations attributable to common shareholders has the effect of making the diluted loss per share less than the basic loss per share. Had we generated income from continuing operations available to common shareholders in the three months ended March 31, 2017, the effect (in thousands) of employee stock options, restricted stock units and deferred compensation units on the diluted shares calculation would have been an increase in shares of 848.
