Pay vs Performance Disclosure, Table
Pay Versus Performance Table
The Company’s compensation philosophy is to pay for performance over the long- and short-term taking into consideration a range of factors, including both financial and non-financial performance measures. We align executive and shareholder interests through a compensation program providing a mix of salary, annual cash bonus incentives, and equity compensation, as further described in the “Compensation Discussion and Analysis” section above.
As required by SEC rules, the table below shows the following information for the past four fiscal years: (i) “total” compensation for our NEOs for purposes of the “Summary Compensation Table”; (ii) the “Compensation Actually Paid” to named executive officers (calculated using rules required by the SEC); (iii) our total shareholder return (“TSR”); (iv) the TSR of the NAREIT All Equity Index; (v) our net income; and (vi) our FFO as adjusted per share. “Compensation Actually Paid” does not represent the value of cash and equity compensation received by named executive officers during the year, but rather is an amount calculated under SEC rules and includes, among other things, year-over-year changes in the value of unvested equity-based awards. As a result of the calculation methodology required by SEC rules, “Compensation Actually Paid” amounts below differ from compensation actually received by the individuals above and the compensation decisions described in the “Compensation Discussion and Analysis” section above.
