Compensation Actually Paid vs. Total Shareholder Return | Compensation Actually Paid vs. Company TSR. As discussed in "VI. Executive Compensation—Compensation Discussion and Analysis," the LTI component of compensation represents the largest portion of the total compensation program for our executives. The majority of LTIs for the periods presented are comprised of Performance RSUs that are tied to the Company's TSR (either absolute or relative to a comparator group). The graph below shows the general alignment between Mr. Brown's CAP and the average CAP for the Company's other NEOs as a group as compared to the returns experienced by our stockholders over the period presented. |  |  |
Compensation Actually Paid vs. Net Income | Compensation Actually Paid vs. Net Income. As shown in the graph below, there is no observed correlation between the fluctuations in the Company's net income and the executives' CAP over the period presented. This is due in large part to the fact that the Company does not use net income as a performance metric for any component of the executives' compensation. |  |  |
Compensation Actually Paid vs. Company Selected Measure | Compensation Actually Paid vs. AFFO per Share. As discussed in "VI. Executive Compensation—Compensation Discussion and Analysis," AFFO per share is one of two financial performance metrics the Company uses to determine annual incentives. However, as a result of the Company's relative emphasis on LTIs as compared to STIs, the impact of AFFO per share improvement on executive compensation can be diminished or completely outweighed in some years. As shown below, despite AFFO per share increases in each of the years presented, significant decreases in the value of outstanding RSUs in 2022 and 2023 caused CAP to be significantly lower than the 2022 and 2021 CAP. |  |  |
Total Shareholder Return Vs Peer Group | Company TSR vs. Peer Group TSR. As shown in the following graph, the Company's cumulative TSR over the period presented underperformed the FTSE NAREIT All Equity REIT Index cumulative TSR. The Company selected this index as its peer group for purposes of the Pay Versus Performance Table, in accordance with the provisions of Item 402(v) of Regulation S-K. The Company does not use the FTSE NAREIT All Equity REIT Index to gauge executive compensation elements or determine the satisfaction of vesting conditions for performance-based awards. For a discussion of the peer groups used by the Company for executive compensation purposes, see "VI. Executive Compensation—Compensation Discussion and Analysis." |  |  |

Additional 402(v) Disclosure | Assumes an initial investment of $100.00 on December 31, 2019 and dividend reinvestment. Alignment Analysis As discussed in "VI. Executive Compensation—Compensation Discussion and Analysis," equity awards represent the largest component of our total compensation program for executives. As a result, fluctuations in our stock price can have a meaningful impact on CAP. This impact is magnified by the Company's selection of TSR (both on an absolute and relative basis) as a performance criteria for a large portion of such equity awards during the periods presented. As a result, year-over-year Company stock price fluctuations can have a material impact on the projected level of vesting of our Absolute TSR Performance RSUs and Relative TSR Performance RSUs. In 2023, our stock price decreased more than the broader equity market. This generally resulted in (1) a decline in the overall value of all outstanding Time RSUs and Performance RSUs; and (2) the value of Performance RSUs held by our NEOs at the end of 2023 being significantly lower than the value of such RSUs at the beginning of 2023. In accordance with Item 402(v) of Regulation S-K, the Company is providing the following descriptions of the relationship between CAP and the financial metrics presented in the Pay Versus Performance Table. The graphs depicted below and related text are (1) based on historical data and are not necessarily indicative of future performance and (2) not to be incorporated by reference into the Company's filings with the SEC, whether made before or after the date hereof, except to the extent that the Company specifically incorporates such disclosure by reference. |  |  |

Non-GAAP Measure Description | The Company has selected "AFFO per share" as the company-selected measure for purposes of this disclosure. We define AFFO per share as AFFO divided by diluted weighted-average common shares outstanding. We define AFFO as Funds from Operations ("FFO") before straight-lined revenues, straight-lined expenses, stock-based compensation expense, net, non-cash portion of tax provision, non-real estate related depreciation, amortization and accretion, amortization of non-cash interest expense, other (income) expense, (gains) losses on retirement of long-term obligations, net (gain) loss on interest rate swaps, (gains) losses on foreign currency swaps, impairment of available-for-sale securities, acquisition and integration costs, restructuring charges (credits), net (income) loss from discontinued operations, (gain) loss on sale of discontinued operations, cumulative effect of a change in accounting principle and adjustments for noncontrolling interests, less sustaining capital expenditures. We define FFO as net income (loss) plus real estate related depreciation, amortization and accretion and asset write-down charges, less noncontrolling interest and cash paid for preferred stock dividends (in periods where applicable), and is a measure of funds from operations attributable to the Company's common stockholders. |  |  |
