Pay vs Performance Disclosure, Table | Pay Versus Performance Our Chief Executive Officer is our principal executive officer ("PEO"). The following table details, for our PEO and our Non-PEO NEOs (on an average basis), total compensation as set forth in the Summary Compensation Table, "compensation actually paid" as determined under SEC rules, cumulative Total Shareholder Return ("TSR"), the cumulative TSR of our peer group, net income, and funds from operations ("FFO") per share, as adjusted, which is the most important financial performance measure that we use to link compensation to performance.

| (2) | Amounts represent "compensation actually paid" for the relevant fiscal year, as determined under SEC rules and calculated per the adjustments detailed below. Our NEOs do not participate in a defined benefit plan. Dividends on unvested awards are included within "All Other Compensation" in the Summary Compensation table. Therefore, no adjustments for pension benefits or dividends paid are included in the table below. The following table details the adjustments made to calculate "compensation actually paid":

| (a) | For equity awards issued during the relevant year, represents fair value of such awards as of the end of the year. For equity awards issued in prior years, represents the change in fair value of such awards as of the vesting date or the end of the year, as appropriate, compared to the fair value of such awards at the end of the prior year. The fair value of the restricted share awards was determined by the closing price of our common shares as of the end of each year. The fair values of option and performance unit awards were calculated using Black-Scholes and Monte Carlo values, respectively, as of the relevant dates, except in the case of the final results of the performance units, which were valued as the closing price of our common shares as of the end of the performance period multiplied by the final multiplier derived from the relative TSR results.

| (4) | TSR is determined based on an initial fixed investment of $100 on December 31, 2019. The TSR peer group consists of the FTSE NAREIT All Equity REIT Index, which is the peer group used for purposes of Item 201(e) of Regulation S-K under the Exchange Act in our Annual Report on Form 10-K for the year ended December 31, 2024.
| (5) | FFO as adjusted, per share is a non-GAAP financial measure. See Appendix A to this proxy statement for a reconciliation of FFO, as adjusted, to net income attributable to common shareholders.
