Between 0% and 200% of the target number of PSUs granted, which were granted under the Issuer's Amended and Restated 2019 Omnibus Compensation Plan (the "Plan"), eligible to vest based on continued employment and the Issuer's annualized total shareholder return over the period from January 1, 2024, through December 31, 2026. ( 3 )Includes an award of 141 dividend equivalent shares accrued on PSU's granted to the Reporting Person under the Issuer's Plan and the Issuer's Dividend and Distribution Reinvestment Plan. Each dividend equivalent unit reflects the right to receive Class A Common Stock, subject to the terms and conditions (including vesting and settlement terms) applicable to the corresponding PSU. During the 2-year vesting period the award will be credited with dividend equivalents that will be paid out in Class A Common Stock at the time the underlying units vest and shares are issued. The award and credited dividend will be payable on a one-to-one basis of Class A Common Stock for each vested PSU, including PSUs, resulting from dividend equivalents.
