_______________________________________


(a)	For the nine months ended September 30, 2018 and the three and nine months ended September 30, 2017, Mattel did not allocate its net loss to its participating RSUs as its participating RSUs are not obligated to share in Mattel's losses. As of July 1, 2018, Mattel no longer has participating RSUs.

(b)

Mattel was in a net loss position for the nine months ended September 30, 2018 and the three and nine months ended September 30, 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 22.6 million shares were excluded from the calculation of diluted net income per common share for the three months ended September 30, 2018 because their effect would be antidilutive.
