Peer Group Issuers, Footnote |  |  | The Peer Group TSR set forth in the table above utilizes the S&P Composite 1500 Property & Casualty Insurance Index, which we also use for the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report on Form 10-K, for the year ended December 31, 2024. The comparison assumes $100 was invested for the period starting December 31, 2019, through the end of the listed year in the company and in the S&P Composite 1500 Property & Casualty Insurance Index, respectively. All dollar values assume reinvestment of the pre-tax value of dividends paid by companies, where applicable, included in the S&P Composite 1500 Property & Casualty Insurance Index. Historical stock performance is not necessarily indicative of future stock performance. This index is not the Peer Group used by the Committee to determine performance-based compensation awards. |  |  |  |
Adjustment To PEO Compensation, Footnote |  |  | The amounts shown for Compensation Actually Paid (CAP) have been calculated in accordance with Item 402(v) of Regulation S-K and do not reflect compensation actually earned, realized, or received by the company’s CEOs or Other NEOs. These amounts reflect the Summary Compensation Table total with certain adjustments as described in footnote 3 below.CAP reflects the exclusions and inclusions of certain amounts for the CEOs and the Other NEOs as set forth below. Equity values are calculated in accordance with FASB ASC Topic 718. Amounts in the Exclusion of Stock Awards and Option Awards column are the totals from the Stock Awards and Option Awards columns set forth in the Summary Compensation Table for the listed year. Amounts in the Exclusion of Change in Pension Value column reflect the amounts attributable to the Change in Pension Value reported in the Summary Compensation Table for the listed year. Amounts in the Inclusion of Pension Service Cost are based on the service cost for services rendered during the listed year.

Compensation Actually Paid vs. Total Shareholder Return |  |  | CAP and Cumulative TSR As shown in the charts below, the CEO and Other NEOs’ CAP amounts are generally aligned with the company’s TSR. This is due primarily to the company's use of equity incentives, which are tied directly to stock price in addition to the company’s financial performance. As described in more detail in Compensation of Named Executive Officers, Compensation Discussion and Analysis, Long-Term Stock-Based Compensation beginning on Page 44, the Committee selected 3-year TSR relative to the Peer Group as the performance objective for performance-based restricted stock units that were granted in the listed years. The same measure also applied to performance-based restricted stock units that vested during the listed years. |  |  |  |
Compensation Actually Paid vs. Net Income |  |  | CAP and Net Income As shown in the charts below, the company’s net income has varied significantly in the years presented. This is due in large part to the inclusion of the change in fair value in our equity portfolio in the net income calculation in accordance with FASB, ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities. Stock market volatility throughout the period also affected the valuations of outstanding equity incentives. The Committee does not use net income as a performance objective in any of the performance-based compensation awards. |  |  |  |
Compensation Actually Paid vs. Company Selected Measure |  |  | CAP and VCR As shown in the charts below, the CEO and Other NEOs’ CAP amounts are generally aligned with the company’s VCR. This is due primarily to the contribution of the changes in book value to the VCR calculation, which includes the changes in fair value in the company’s equity portfolio. As described in more detail in Compensation of Named Executive Officers, Compensation Discussion and Analysis, beginning on Page 33, the committee selected VCR relative to the peer group as the performance objective for annual incentive compensation awards that were granted in the listed years. |  |  |  |

Non-GAAP Measure Description |  |  | Financial Performance Measures As described in greater detail in “Compensation of Named Executive Officers – Compensation Discussion and Analysis,” the company’s executive compensation program is based on a pay-for-performance philosophy. The metrics that the company uses for both our short-term and long-term performance-based awards are selected to incentivize achievement of both short-term and long-term performance objectives that create value for our enterprise and our shareholders. For 2024, we determined VCR to be the most important financial performance measure used to link company performance to CAP for our CEO and Other NEOs. This performance measure may not have been the most important financial performance measure for years 2020 through 2023, and we may determine a different financial performance measure to be the most important financial performance measure in future years. The Committee established relative VCR compared with the nine companies included in company’s Peer Group as the primary performance objective for annual incentive compensation awards. The relative VCR placement earned payouts at maximum levels for the CEOs and the Other NEOs for 2024. The Committee does not use the S&P Composite 1500 Property & Casualty Insurance Index in setting targets or objectives for performance-based compensation. See Compensation of Named Executive Officers, Compensation Discussion and Analysis, Benchmarking and Peer Group beginning on Page 51 for more information about the Committee's selection and use of the Peer Group in making compensation decisions. Analysis of the Information Presented in the Pay Versus Performance Table While the Committee uses several performance measures to align executive compensation with company performance, including VCR and 3-year TSR achievement relative to the companies in the Peer Group, not all of those performance measures are presented in the Pay Versus Performance Table and therefore the company’s performance measures do not necessarily align with CAP as calculated in accordance with Item 402(v) of Regulation S-K for a particular year. In accordance with Item 402(v) of Regulation S-K, the company is providing the following descriptions of the relationships between information presented in the Pay Versus Performance Table. |  |  |  |
