Additional 402(v) Disclosure For each Covered Year, our total shareholder return was calculated as the yearly percentage change in our cumulative total shareholder return on our common stock, measured as the quotient of (a) the sum of (i) the cumulative amount of dividends for a period beginning with our closing price on NYSE on December 31, 2019 through and including the last day of the fiscal year covered (the “Measurement Period”), assuming dividend reinvestment, plus (ii) the difference between our closing stock price at the end versus the beginning of the Measurement Period ($112.61 per share and $55.79 per share, respectively), divided by (b) our closing share price at the beginning of the Measurement Period ($55.79 per share). Each of these yearly percentage changes was then applied to a deemed fixed investment of
$100 at the beginning of the Measurement Period to produce the Covered Year-end values of such investment as of the end of 2024, 2023, 2022, 2021 and 2020, as applicable. Because Covered Years are presented in the table in reverse chronical order (from top to bottom), the table should be read from bottom to top for purposes of understanding cumulative returns over time.
As a result of SEC Guidance released in November of 2023, the Compensation Actually Paid figures related to 2022 have been revised to account for the change in value of PSUs between the end of their measurement period, in this instance December 31, 2022, and their February 2023 distribution date.
