Explanation of Responses:

( 1 )On April 3, 2019, the reporting person was granted 27,618 time-based restricted stock units ("RSUs"), which vest in three equal installments on March 31 of each of 2020, 2021 and 2022 and are subject to continued employment through the vesting date. Each RSU represents a contingent right to receive one share of the issuer's common stock. The RSUs may be settled in shares of the issuer's common stock or cash (at the election of the issuer). The issuer's Compensation Committee elected to settle the RSUs that vested on March 31, 2020 in shares of the issuer's common stock. ( 2 )On April 3, 2019, the reporting person was granted cash-based performance awards ("Performance Awards"), which vest in three equal installments on March 31 of each of 2020, 2021 and 2022 and are subject to continued employment through the vesting date. The Performance Awards may be settled in cash or shares of the issuer's common stock (at the election of the issuer). The Compensation Committee determined that a portion of the first installment of the Performance Awards vested, based on the issuer's achievement of the relevant performance conditions, and elected to settle such Performance Awards in shares of the issuer's common stock. The number of shares received was based on the closing price of the issuer's common stock on March 31, 2020. ( 3 )Reflects withholding of shares by the issuer to offset the tax liability resulting from the vesting on March 31, 2020 with respect to (i) 9,206 time-based RSUs granted on April 3, 2019; (ii) 8,767 time-based RSUs granted on June 20, 2018; and (iii) 27,243 Performance Awards. ( 4 )Previously reported as "phantom stock units." The correct title of these securities is "restricted stock units." ( 5 )On March 31, 2020, the reporting person was granted 45,573 time-based RSUs, which vest in three equal installments on June 30, 2021 and March 31 of each of 2022 and 2023 and are subject to continued employment through the vesting date. Each RSU represents a contingent right to receive one share of the issuer's common stock. The RSUs may be settled in shares of the issuer's common stock or cash (at the election of the issuer).
