Additional 402(v) Disclosure | In accordance with new SEC rules, the following table and accompanying discussion and charts provide information on the relationship between the “compensation actually paid” to our NEOs (calculated in accordance with Item 402(v) of Regulation S-K) and certain measures of the Company’s financial performance, including Total Shareholder Return, Net Income and a Company-Selected Metric that is most important to the determination of executive compensation (in the Company’s case, Adjusted Pretax Income). The compensation actually paid (“CAP”) set forth in the table below does not reflect amounts actually realized by our NEOs, and the HR Compensation Committee did not consider CAP when making compensation decisions for any of the years presented.Reflects total shareholder return (“TSR”) calculated in the manner required by Item 201(e) of Regulation S-K and reflects the cumulative value of $100, including the reinvestment of dividends, if such amount were invested on September 30, 2020.Reflects consolidated net income calculated in accordance with GAAP for each of the years shown. |  |
Measure:: 1 |  |  |
