| Tabular List [Table Text Block] | Performance Measures Used for Linking Pay and Performance. The following is a list of performance measures, which in our assessment represent the most important performance measures used by our Company to link compensation actually paid to our PEO and the NEOs for 2022. Each metric below is used for purposes of determining payouts under either our annual cash incentive program or vesting of our performance-based LTIP Units. FFO per share was selected as our Company-Selected Measure for the Pay versus Performance table because it has the strongest alignment with the key attributes of our operating plan and we believe that it drives the creation of long-term stockholder value . FFO per Diluted Share Year-end Relative TSR Re-development Net Debt Reduction ESG Initiatives Please see our Compensation Discussion and Analysis on page 33 of this proxy statement for a further description of these metrics, how they are calculated, and how they are used in our executive compensation pro gr | ||
