(1)		On October 3, 2011, we completed the acquisition of Diversey. Under the terms of the acquisition agreement, we paid in aggregate, $2.1 billion in cash consideration and an aggregate of 31.7 million shares of our common stock, to the shareholders of Diversey. The shares included in the total consideration have not been included in the diluted earnings per share calculation above. These shares are issued and outstanding as of October 3, 2011.

PSU Awards

Since the PSU awards discussed in Note 14, “Stockholders’ Equity,” are contingently issuable shares that are based on a condition other than earnings or market price, these shares will be included in the diluted weighted average number of common shares outstanding when they have met the performance conditions as of these dates. The shares for the 2009 three-year PSU awards and the shares for the 2010 three-year PSU awards are included in the diluted weighted average number of common shares outstanding for the three and nine months ended September 30, 2011 because the target levels of their respective performance conditions were met as of September 30, 2011. The shares for the 2011 three-year PSU awards have not been included in the diluted weighted average number of common shares outstanding in the three and nine months ended September 30, 2011 because they have not met the target levels of their performance conditions as of these dates.

SLO Awards

The shares or units associated with the 2011 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, 2011. These shares or units, discussed in Note 14, “Stockholders’ Equity,” 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 the following year. Once this determination is made, the shares or units will be included in the basic 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. The numbers of shares or units associated with SLO awards for the 2010 and earlier fiscal years that were included in the common shares outstanding for the three and nine months ended September 30, 2011 and 2010 were nominal.
