[1] Preferred stock dividends were not added back in the calculation of diluted earnings per share for the periods ended December 31, 2012 and 2011 because the effect of adding them back would have been antidilutive.

[2] Deferred stock awards are considered participating securities due to Dow's practice of paying dividend equivalents on unvested shares.
