Explanation of Responses:
(1)	As the result of an administrative error, the Form 3 filed by the Reporting Person with the Securities and Exchange Commission ("SEC") on June 13, 2018 contained an error in this footnote that described the schedule of vesting of these restricted stock units ("RSUs"). This amended report provides the corrected footnote.
(2)	33.3% of the RSUs vested on December 31, 2018, 33.3% of the RSUs will vest on December 31, 2019 and the remaining 33.3% of the RSUs will vest on December 31, 2020. Shares of the Issuer's Class B common stock will be delivered to the Reporting Person following vesting, at which time shares will be automatically sold on behalf of the Reporting Person to cover any tax withholding obligations.
(3)	Each RSU represents a contingent right to receive 1 share of the Issuer's Class B common stock upon settlement for no consideration.
