| | <footnote id="F1"> On April 3, 2019, the reporting person was granted 26,818 time-based restricted stock units ("RSUs"), each of which represents a contingent right to receive one share of the issuer's common stock and which vest in three equal installments on March 31 of each of 2020, 2021 and 2022, subject to continued employment through the vesting date. 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, 2021 in shares of the issuer's common stock. </footnote> |
| | <footnote id="F2"> 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 the second installment of the Performance Awards vested in full, 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, 2021. </footnote> |
| | <footnote id="F3"> Reflects withholding of shares by the issuer to offset the tax liability resulting from the vesting on March 31, 2021 with respect to: (i) 10,112 time-based RSUs granted on June 20, 2018; (ii) 8,939 time-based RSUs granted on April 3, 2019; (iii) 14,326 time-based RSUs granted on March 31, 2020; and (iv) 11,971 Performance Awards. </footnote> |
| | <footnote id="F4"> On March 31, 2020, the reporting person was granted 42,979 time-based RSUs, each of which represents a contingent right to receive one share of the issuer's common stock and which vest in three equal installments on March 31 of each of 2021, 2022 and 2023, subject to continued employment through the vesting date. The Form 4 filed by the reporting person on April 2, 2020 inadvertently stated that the first tranche would vest on June 30, 2021. 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, 2021 in shares of the issuer's common stock. </footnote> |
| | <footnote id="F5"> On March 31, 2021, the reporting person was granted 22,759 time-based RSUs, each of which represents a contingent right to receive one share of the issuer's common stock and which vest in full on March 31, 2024, subject to continued employment through the vesting date. The RSUs may be settled in shares of the issuer's common stock or cash (at the election of the issuer). </footnote> |
| | <footnote id="F6"> Each performance-based RSU represents a contingent right to receive one share of the issuer's common stock. The applicable performance goal was to be satisfied if the issuer's common stock achieves a specified per share market price for any period of 30 consecutive trading days prior to June 30, 2021 (the "2018 performance goal"), subject to continued employment through the vesting date. In March 2021, the issuer's Compensation Committee approved a modification of the vesting terms, such that, if the Company has not achieved the performance goal by December 31, 2022, all unvested performance-based RSUs will be forfeited. </footnote> |
