| Pay vs Performance [Table Text Block] | Pay Versus Performance The following table sets forth information regarding our performance and the “compensation actually paid” to our named executive officers, as calculated in accordance with SEC disclosure rules: Value of Initial Fixed $100 (4) Year (1) Summary (2) Compensation (3) Average (2) Average (3) Total Peer Group (5) Net Income Change in (6) 2022 10,130,622 10,086,031 3,373,344 3,575,079 96.58 144.67 (1,159,816 ) (19.7 )% 2021 8,908,774 8,210,429 2,963,222 2,784,054 87.91 126.01 (103,440 ) (3.5 )% 2020 9,573,736 5,911,812 3,429,817 2,394,301 85.30 105.39 993,058 16.0 % (1) Kevin J. O’Donnell has served as our principal executive officer for the entirety of 2020, 2021 and 2022. Our other named executive officers for the applicable years were as follows: - 2022: Robert Qutub; Ross A. Curtis; Ian D. Branagan; and Sean G. Brosnan - 2021: Robert Qutub; Ross A. Curtis; Ian D. Branagan; and Sean G. Brosnan - 2020: Robert Qutub; Ross A. Curtis; Ian D. Branagan; and Stephen H. Weinstein (2) Amounts reported in this column represent (i) the total compensation reported in the Summary Compensation Table for the applicable year in the case of Mr. O’Donnell and (ii) the average of the total compensation reported in the Summary Compensation Table for the applicable year for our other named executive officers for the applicable year. (3) To calculate the compensation actually paid (“CAP”), adjustments were made to the amounts reported in the Summary Compensation Table for the applicable year. A reconciliation of the adjustments for Mr. O’Donnell and for the average of the other named executive officers is set forth following the footnotes to this table. (4) Pursuant to rules of the SEC, the comparison assumes $100 was invested on December 31, 2019. Historic stock price performance is not necessarily indicative of future stock price performance. (5) The TSR peer group consists of the S&P 1500 Property & Casualty Insurance Index, an independently prepared index that includes companies in the property and casualty insurance industry (and which is used for the Company’s stock performance chart in the annual report). (6) As noted in “Executive Compensation—Compensation Discussion and Analysis,” the Governance and Human Capital Committee selected change in book value per common share plus change in accumulated dividends as a key metric for evaluating and rewarding management’s performance in the 2022 incentive program design. This measure is used to determine the vesting of 75% of the performance share awards, the most heavily weighted component of our executive compensation program.

| Compensation Actually Paid vs. Total Shareholder Return [Text Block] | Below is a description of the relationships between executive compensation actually paid by us to the PEO and the average of the executive compensation actually paid to the named executive officers other than the PEO, and the cumulative total shareholder return; net income (loss); and change in book value per share plus change in accumulated dividends. As described in “Executive Compensation—Compensation Discussion and Analysis”, our executive compensation program is heavily weighted towards long-term incentive awards that are settled in stock. Given this weighting towards long-term incentives, our compensation actually paid is less impacted by our net income and change in book value per share plus change in accumulated dividends and most greatly impacted by changes in our stock price.
