Pay vs Performance Disclosure [Table] | | | | | |
Pay vs Performance [Table Text Block] | | | Pay versus Performance The SEC adopted new disclosure on August 25, 2022 for proxy statements filed with respect to fiscal years ending on or after December 16, 2022 with a new Pay Versus Performance ("PVP") rule. The rule requires a new table and narrative disclosure comparing Compensation Actually Paid ("CAP") against company performance. The Company is required to provide additional disclosure regarding the relationship between NEO CAP and net earnings, cumulative TSR and Core FFO. In addition, the Company must provide at least three, but not more than seven, of the most important company measures used to determine NEO pay. At least three of these measures must be financial measures. Below are the tables and related footnotes for PVP: Julian Whitehurst (2) Stephen Horn (3) Average SCT Total for Value of Initial Fixed $100 Investment Base On: Year SCT Total for CEO CAP to CEO (2) SCT Total for CEO CAP to CEO (3) Non-CEO NEOs Average CAP to Non-CEO NEOs The Company TSR Peer Group TSR (1) Net Income Core FFO per Share 2022 $ 5,010,993 $ 9,118,484 $ 6,776,699 $ 8,868,801 $ 2,544,244 $ 3,624,286 $ 99.13 $ 100.62 $ 334,626,000 $ 3.14 2021 $ 7,785,586 $ 7,727,120 - - $ 2,591,922 $ 2,682,871 $ 99.22 $ 134.06 $ 264,217,000 $ 2.86 2020 $ 5,594,166 $ 2,108,174 - - $ 2,344,128 $ 1,166,529 $ 80.65 $ 94.88 $ 210,859,000 $ 2.59 (1) NNN’s peer group TSR is based on FNER, which is the index used for purposes of the performance graphs in Part II, Item 5 of the Company's Annual Report on Form 10-K for the year ended December 31, 2022 and the Compensation Discussion and Analysis.

Compensation Actually Paid vs. Total Shareholder Return [Text Block] | | | The reported amount of compensation actually paid to our CEO, and the reported average amount of compensation actually paid to our non-CEO executive officers, is primarily driven by the value of our executives’ unvested equity. Further, as discussed in the Compensation Discussion and Analysis, our TSR is a component metric in our long-term incentive plan, and Core FFO per share is a component metric of our cash incentive bonus. As a result, the TSR figures reported above have a strong correlation to our executives’ compensation actually paid, while Core FFO per share has a lesser degree of impact on and correlation to the compensation actually paid figures. While our TSR lagged behind the above reported peer group TSR for 2020 and 2021, our resilience in 2022 resulted in a cumulative 2022 three-year TSR on par with the reported peer group. | | |
