(1) On December 30, 2016, the Company converted its outstanding shares of Cumulative Convertible Perpetual Preferred Stock, Series A ("Preferred Stock") into shares of the Company's common stock. As a result of this conversion, no shares of Preferred Stock are issued or outstanding.

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

(3) These outstanding options to purchase shares of common stock and deferred stock awards were excluded from the calculation of diluted earnings per share because the effect of including them would have been antidilutive.
