| Pay vs Performance Disclosure [Table] | |||
| Pay vs Performance [Table Text Block] | Pay Performance In August 2022, the SEC adopted pay versus performance disclosure rules that require us to provide the information set forth in the table below. The rules require disclosure for each of the Company’s five most recently completed fiscal years. For the initial disclosure, however, we are only required to provide disclosure for the prior three years, with an additional year added in each of the two subsequent years.

Our management fee revenue is calculated as a percentage – limited to 25 percent—of all direct written premiums of the Property and Casualty Group. The management fee rate was set at 25 percent for 2022, 2021 and 2020. DWP is adjusted slightly for purposes of computing the Company’s management fee revenue. The adjustments include change in estimate for management fee returned on cancelled policies and the timing of revenue recognized for the administrative services. | ||

| Compensation Actually Paid vs. Company Selected Measure [Text Block] | Direct Written Premium Growth For purposes of this Pay versus Performance disclosure, we are required to identify a “Company Selected Measure” from among the measures linked to executive compensation (see Compensation Discussion and Analysis). DWP growth for the Property and Casualty Group is the selected measure. Although there are other financial performance measures providing important linkage to executive compensation (see Other Measures), they do not fit the SEC definition of a “Company Selected Measure.” DWP is included in both the AIP and LTIP (see Annual Incentive Plan and Long Term Incentive Plan in the Compensation Discussion and Analysis). The graph above illustrates the directional relationship between our CEO and average non-CEO Under the AIP, DWP is weighted at 35 percent (50 percent in 2020) of the total company performance measures and 28 percent of the total target AIP award for our NEOs. Each year, the compensation committee established a minimum, or “threshold,” a target, and a maximum level of payout for each performance measure. DWP increased 1.8 percent in 2020 compared to 2019. Since the threshold for that metric was set at 2.4 percent, there was no payout for that performance measure for the 2020 plan year. The below target premium growth was impacted by rate reductions implemented for personal and commercial auto policies in response to reduced driving conditions resulting from the Covid-19 DWP increased 3.3 percent in 2021 compared to 2020. The AIP target for that performance measure was set at 2.2 percent and the maximum at 4.2 percent, resulting in a 155 percent payout for that metric for the 2021 plan year, which is reflected in the compensation actually paid calculation for 2021. For the LTIP three-year performance period that ended December 31, 2021, the Property and Casualty Group underperformed the peer group by 247 basis points. The DWP target in the 2022 AIP was set at 6.7 percent and the maximum was set at 9.7 percent. Actual 2022 DWP growth was 9.2 percent, resulting in a 183 percent payout for that metric for the 2022 plan year which is reflected in the compensation actually paid calculation for 2022. For the three-year LTIP performance period that ended December 31, 2022, we are projecting that the Property and Casualty Group will underperform the peer group. | ||
| Total Shareholder Return Vs Peer Group [Text Block] | Total Shareholder Return – Company versus Peer Group The Standard & Poor’s Supercomposite Insurance Industry Group Index is made up of 55 constituent members comprised of property and casualty insurers, insurance brokers, and life insurers, and is a capitalization weighted index. The Standard & Poor’s Supercomposite Insurance Industry Group Index is not our Executive Compensation Benchmarking Peer Group. Instead, we use compensation data for a peer group of property and casualty companies that we consider to be our competitors for policyholders, and in some cases, employees, and similar to us in terms of lines of business, net premiums written and/or asset size. See Compensation Discussion and Analysis — 2022 Executive Compensation Benchmarking Peer Group. Since several of the companies in our 2022 Executive Compensation Benchmarking Peer Group are not publicly traded, there is no way to compute TSR for our 2022 Executive Compensation Benchmarking Peer Group. While we do not benchmark executive compensation to Standard & Poor’s Supercomposite Insurance Industry Group Index, we believe that the composition of the selected index is a suitable comparison for TSR as it broadly reflects our operations serving as attorney-in-fact | ||
