F1923 shares of the restricted share unit ("RSU") grant, which represent approximately 33% of the shares underlying the RSU grant that vested on January 11, 2018, were not issued to the reporting holder; instead the reporting holder received an amount in cash from the issuer equal to the value of such shares based on the closing price of the issuer's Common Stock on January 11, 2018 to facilitate such holder's satisfaction of U.S. federal income tax obligations in connection with the vesting of the RSUs, which transaction does not represent a sale by the reporting person.
F2Approximately 67% of each RSU represents a contingent right to receive approximately 0.67 share of the issuer's Common Stock upon vesting and approximately 33% represents a contingent right to receive cash upon vesting, which cash will be used to facilitate the holder's satisfaction of U.S. federal tax obligations in connection with the vesting of the RSUs.
F3Twenty-five percent of the shares underlying the RSU vest on each of January 11, 2018, January 11, 2019, January 11, 2020 and January 11, 2021, subject to the holder's continued employment with the issuer on each vesting date.
