[1] For 2013 and 2014, pro forma earnings per share (EPS) was calculated based on 180,966,833 shares of Chemours common stock that were distributed to DuPont shareholders on July 1, 2015.

[2] Diluted (loss) earnings per share is calculated using net (loss) income available to common shareholders divided by diluted weighted-average shares of common shares outstanding during each period, which includes unvested restricted shares. Diluted earnings per share considers the impact of potentially dilutive securities except in periods in which there is a loss because the inclusion of the potential common shares would have an antidilutive effect. Chemours had no equity awards outstanding prior to the spin-off.
