⁽¹⁾	In calculating diluted net earnings (loss) per common share for 2012, our diluted weighted average number of common shares outstanding excludes the effect of assumed issuance of shares under the Settlement agreement and non-vested restricted stock units as the effect was anti-dilutive.

PSU Awards

Since the PSU awards include contingently issuable shares that are based on conditions other than earnings or market price, they are included in the diluted weighted average number of common shares outstanding when we meet the performance conditions as of that date. However, in 2012, unvested PSU awards that met the performance conditions as of September 30, 2012 were not included in the diluted weighted average number of common shares outstanding for the three and nine months ended September 30, 2012 as the effect was anti-dilutive.

Stock Leverage Opportunity Awards

The shares or units associated with the 2013 SLO awards are considered contingently issuable shares and therefore are not included in the basic or diluted weighted average number of common shares outstanding for the three and nine months ended September 30, 2013. These shares or units will not be included in the common shares outstanding until the final determination of the amount of annual incentive compensation is made in the first quarter of 2014. Once this determination is made, the shares or units will be included in both the basic and diluted weighted average number of common shares outstanding if the employee is retirement eligible or in the diluted weighted average number of common shares outstanding if the employee is not retirement eligible if the impact to diluted net earnings per common share is dilutive. The numbers of shares or units associated with SLO awards for the three and nine months ended September 30, 2013 and 2012 were nominal and, for the three and nine months ended September 30, 2012, have not been included in the diluted weighted average number of common shares outstanding as the effect was anti-dilutive.
