Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies The Company is, from time to time, named as a defendant in various lawsuits or regulatory actions incidental to its insurance business. The majority of lawsuits brought against the Company relate to insurance claims that arise in the normal course of business and are reserved for through the reserving process. For a discussion of the Company’s reserving methods, see the Company’s Annual Report on Form 10-K for the year ended December 31, 2021. On September 10, 2021, the California Department of Insurance ("DOI") served the Company a Notice of Non-Compliance ("NNC"), alleging violations in connection with its 2014 Rating & Underwriting Examination Report, which was adopted by the California DOI in 2019. The NNC itemizes alleged violations, many of which management believes were corrected or otherwise resolved during the course of the examination, and seeks penalties. The Company has participated in lengthy and detailed discussions with the California DOI since the adoption of the examination report, in an attempt to address the issues deemed unresolved by the California DOI, and has taken several additional corrective actions approved by the California DOI. The Company is continuing discussions with the California DOI in order to resolve the outstanding issues, or at least obtain the agreement of the California DOI to remove the resolved items from the NNC before proceeding to a formal hearing process if a settlement is not reached. The Company cannot reasonably predict the outcome of the hearing if it occurs, nor can it reasonably estimate the amount of penalties, if any. On October 5, 2021, the Company received a letter from the California DOI requesting additional information on the amount of premium refunds or credits that the Company has provided or plans to further provide to its private passenger automobile policyholders, and the methodology used in determining such refunds or credits for the time period of March 2020 through at least March 2021, due to reduced driving during the pandemic. On October 6, 2021, the California DOI issued a press release alleging that the Company and two other insurers have not provided enough premium relief to the policyholders through premium refunds or credits for lower frequency resulting from reduced driving during the pandemic. Two private actions against the Company were also filed during the first quarter of 2022, asserting substantially the same arguments on behalf of an alleged class of similarly situated policyholders, and seeking restitution of the allegedly excessive premiums charged during the pandemic. The Company believes that the amounts returned to-date, including the mileage reductions on individual policies, have provided appropriate and material relief to its policyholders and that there is no legal basis for the California DOI or the courts to require the Company to issue additional refunds. The total amount of premiums returned to the Company's policyholders through refunds or credits is approximately $128 million, which reduced its net premiums earned for 2020. The Company has also worked with its agents and policyholders to reclassify exposures on an individual policy basis, including reducing mileage on a large number of vehicles since the pandemic began. Management believes the mileage reductions have significantly reduced premiums on those individual policies in a manner consistent with the Company’s filed and approved rates. However, the Company cannot predict whether or not the California DOI or private plaintiffs will take further actions against the Company related to the premium refunds and credits, which may include inducing the Company to provide additional premium refunds to its policyholders, nor can it reasonably estimate the amount of such additional refunds or other losses, if any, due to any potential actions by the California DOI or the courts and the Company's responses to such actions. The Company establishes reserves for non-insurance claims related lawsuits, regulatory actions, and other contingencies when the Company believes a loss is probable and is able to estimate its potential exposure. For loss contingencies believed to be reasonably possible, the Company also discloses the nature of the loss contingency and an estimate of the possible loss, range of loss, or a statement that such an estimate cannot be made. In addition, the Company accrues for anticipated legal defense costs associated with such lawsuits and regulatory actions. While actual losses may differ from the amounts recorded and the ultimate outcome of the Company's pending actions is generally not yet determinable, the Company does not believe that the ultimate resolution of currently pending legal or regulatory proceedings, either individually or in the aggregate, will have a material adverse effect on its financial condition or cash flows. In all cases, the Company vigorously defends itself unless a reasonable settlement appears appropriate. For a discussion of any additional regulatory or legal matters, see the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.
