Total Shareholder Return versus Compensation Actually Paid •We believe the above graph shows that our Named Executive Officer compensation moved generally in tandem with both improving and declining TSR results over the Covered Years. |  |

|  |  | Principal Executive Officer

|  |  | Net Income
Net Income versus Compensation Actually Paid •Net Income (as shown in the table and as the blue line in the graph above) includes the income from discontinued operations, which is comprised of a $550 million gain on the sale of our Distribution business in 2022. Therefore, in 2022, Net Income is not heavily correlated with Named Executive Officer compensation because of this one time gain that is not reflective of the underlying performance of the Company. Named Executive Officer compensation moved generally in tandem with improving results from 2020 to 2021. |  |

Adjusted EPS versus Compensation Actually Paid •We believe the foregoing graph shows that our Named Executive Officer compensation has either tracked or, in the case of 2022, significantly lagged our performance as compared to Adjusted EPS over the Covered Years. |  |

Additional 402(v) Disclosure [Text Block] | 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, par value $0.01 per share, measured as the quotient of (a) the sum of (i) the cumulative amount of dividends for a period beginning with our closing price on the New York Stock Exchange (“NYSE”) on December 31, 2019 through and including the last day of the Covered Year (each one-year, two-year, and three-year period, a “Measurement Period”), assuming dividend reinvestment, plus (ii) the difference between our closing stock price at the end versus the beginning of the Measurement Period, divided by (b) our closing share price at the beginning of the Measurement Period. 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 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. |  |
