Pay vs Performance Disclosure, Table | PAY VERSUS PERFORMANCE TABLE As required by the Securities and Exchange Commission, the following table is intended to illustrate compensation “actually paid” to our NEOs for each of the fiscal years ended December 31, 2020, 2021, 2022, 2023 and 2024, in each case, as compared to (i) our cumulative TSR performance, (ii) our peer group TSR performance, (iii) net income, and (iv) FFO per share (“FFO”), the company’s selected measure. Differences in our Summary Compensation Table amounts and compensation actually paid reflect changes in the fair value of equity awards, both outstanding and vested in each year, which take into account a discount for lack of marketability or illiquidity due to post-vesting restrictions and the future performance of the Company and relative performance indices based on Monte Carlo simulations for any market-based awards.

For the fiscal year ending December 31, 2024, represents actual achievement for the 2022 PSU awards, assumes achievement of 2023 and 2024 awards based on actual performance of the Company and indices through December 31, 2024 as well as future performance of the Company and indices calculated through Monte Carlo simulation analyses by an independent third party. For the time-based LTIP units, fair value represents stock price at the end of each fiscal year multiplied by an illiquidity discount due to their post-vesting restrictions and a discount for book-up risk, where applicable. The methodology used to develop the valuation assumptions as of each applicable measurement date is consistent with those disclosed at the time of grant. The valuation assumptions used to calculate the fair values were updated as of each measurement date and will differ from those disclosed as of the grant date. For market-based awards, the fair values were calculated by a Monte Carlo simulation model as of the applicable measurement dates, which utilizes multiple input variables, including expected volatility of our stock price and other assumptions appropriate for determining fair value, to estimate the probability of satisfying the performance objective established for the award, including the expected volatility of our stock price relative to the applicable comparative index and a risk-free interest rate. (2) Based on a fixed investment of $100 on December 31, 2019 in the Company’s stock assuming reinvestment of dividends on the ex-dividend date. ​ (3) Based on a fixed investment of $100 on December 31, 2019 in the Dow Jones U.S. Real Estate Office Index, assuming reinvestment of dividends. ​ (4) FFO is a non-GAAP measure. Refer to Appendix A for a definition of FFO and a reconciliation of net income to FFO. |  |  |  |
