For 2014, the shares included above represent the weighted average number of shares from January 1, 2014 through February 3, 2014. The weighted average number of shares from February 4, 2014 through September 30, 2014 are included in the weighted average number of common shares outstanding-basic since they were issued on February 3, 2014 in connection with the Settlement agreement.

PSU Awards

For the three and nine month periods ended September 30, 2014 and 2013, we included contingently issuable shares for our PSU awards in the diluted weighted average number of common shares outstanding based on the number of contingently issuable shares that would be issued assuming the end of our reporting period was the end of the relevant PSU award contingency period.

We included 1.9 million shares in the three months ended September 30, 2014 and 1.8 million shares in the nine months ended September 2014 related to our 2012, 2013 and 2014 PSU awards in the diluted weighted average number of common shares outstanding due to the achievement levels of their respective performance conditions as of September 30, 2014. In 2014, we revised our diluted weighted average number of common shares outstanding to include 1.6 million shares in the three months ended September 30, 2013 and 1.5 million shares in the nine months ended September 30, 2013 related to our 2011, 2012 and 2013 PSU awards in the diluted weighted average number of common shares outstanding due to the achievement levels of their respective performance conditions as of September 30, 2013. During the three months ended September 30, 2014, we determined that we did not include any PSU awards in our diluted weighted average number of common shares outstanding previously reported in 2014 and 2013, although the achievement levels of the respective performance conditions for the PSU awards were met at the end of each of the respective reporting periods in 2014 and 2013. The impact of not including these shares in the previously reported periods in 2014 and 2013 was not material to the calculation of the weighted average shares included in the diluted net earnings per common share under the two-class method and had no impact on diluted net earnings per common share for these periods. Accordingly, we do not consider this correction to be material to our previously reported diluted weighted average number of common shares outstanding or to our previously reported net earnings per common share.

The previously reported, and revised diluted weighted average number of common shares outstanding to include the achievement of PSU awards in each previous reporting period of 2014 and 2013 are as follows:

	2014
	Three Months Ended		Three Months Ended		Six Months Ended
	March 31, 2014		June 30, 2014		June 30, 2014
Previously reported diluted weighted average number of common shares outstanding		214.5		214.7		214.6
Revised diluted weighted average number of common shares outstanding		216.0		216.4		216.2

	2013
	Three Months Ended		Three Months Ended		Six Months Ended		Three Months Ended		Nine Months Ended		Three Months Ended		Year Ended
	March 31, 2013		June 30, 2013		June 30, 2013		September 30, 2013		June 30, 2013		December 31, 2013		December 31, 2013
Previously reported diluted weighted average number of common shares outstanding		212.7		213.6		213.2		213.7		213.4		213.9		213.5
Revised diluted weighted average number of common shares outstanding		214.3		215.0		214.7		215.3		214.9		215.4		215.1

Stock Leverage Opportunity Awards (“SLO”)

The shares or units associated with the 2014 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 months and nine months ended September 30, 2014. 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 2015. Once this determination is made, the shares or units will be included in diluted weighted average number of common shares outstanding 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 months and nine ended September 30, 2014 and 2013 were nominal.
