(a)	For the twelve months ended December 31, 2018 and December 31, 2017, Mattel did not allocate its net loss to its participating RSUs as its participating RSUs are not obligated to share in the losses of the Company. As of July 1, 2018, Mattel no longer has participating RSUs.

(b)

Mattel was in a net loss position for the twelve months ended December 31, 2018 and December 31, 2017, and, accordingly, all outstanding nonqualified stock options and non-participating RSUs were excluded from the calculation of diluted earnings per common share because their effect would be antidilutive. Nonqualified stock options and nonparticipating RSUs totaling 8.5 million shares were excluded from the calculation of diluted net income per common share for the twelve months ended December 31, 2016 because their effect would be antidilutive.
