[1] Includes the weighted-average share impact in 2012 of 31.7 million shares issued as part of the total consideration paid in connection with the acquisition of Diversey on October 3, 2011.

[2] Provides for the following items if their inclusion is dilutive: (i) the effect of assumed issuance of 18 million shares of common stock reserved for the Settlement agreement as defined and (ii) the effect of non-vested restricted stock and restricted stock units using the treasury stock method. In calculating diluted net (loss) earnings per common share for 2012, our diluted weighted average number of common shares outstanding excludes the effect of the items mentioned above as the effect was anti-dilutive.
