Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Leases The Company is obligated under various non-cancellable lease agreements providing for office space, automobiles, office equipment, and EDP equipment that expire at various dates through the year 2028. See Note 7. Leases for additional information on leases and future lease payments as of December 31, 2020. California Earthquake Authority ("CEA") The CEA is a quasi-governmental organization that was established to provide a market for earthquake coverage to California homeowners. The Company places all new and renewal earthquake coverage offered with its homeowners policies directly with the CEA. The Company receives a small fee for placing business with the CEA, which is recorded as other income in the consolidated statements of operations. Upon the occurrence of a major seismic event, the CEA has the ability to assess participating companies for losses. These assessments are made after CEA capital has been expended and are based upon each company’s participation percentage multiplied by the amount of the total assessment. Based upon the most recent information provided by the CEA, the Company’s maximum total exposure to CEA assessments at April 28, 2020, the most recent date at which information was available, was approximately $78.0 million. There was no assessment made in 2020. Regulatory Matters On April 13, 2020, the California Insurance Commissioner issued Bulletin 2020-3 ordering insurers to make an initial premium adjustment within 120 days from the date of the Bulletin 2020-3 to adversely impacted California policyholders for the months of March and April 2020. The Commissioner granted insurers flexibility in determining how to quickly and fairly process the premium refunds. On May 15, 2020, the California Insurance Commissioner issued Bulletin 2020-4 extending the directives in Bulletin 2020-3 through May 31, 2020. The Bulletin 2020-8, originally issued on June 25, 2020 and amended on December 3, 2020, extended the previous directives of Bulletin 2020-3 and Bulletin 2020-4 through June 30, 2020, as well as any months subsequent to June 2020 because the COVID-19 pandemic continued to result in projected loss exposures remaining overstated or misclassified. The total amount of premiums returned to the Company's policyholders through refunds or credits in 2020 was approximately $128 million. The Company's net premiums earned was reduced by approximately $128 million for the twelve months ended December 31, 2020 as a result of these premium refunds and credits. In November and December 2020, the California Insurance Commissioner issued a mandatory moratorium on cancellations and non-renewals of policies of residential property insurance after the declaration of a state of emergency through Bulletins 2020-11, 2020-12 and 2020-13. These Bulletins list declarations of a state of emergency issued by the California Governor in August, September and November 2020, along with the ZIP Codes within and adjacent to the fire perimeters in counties subject to each state of emergency. The mandatory moratorium prohibits insurers from canceling or refusing to renew a policy of residential property insurance for a property located in any ZIP Code listed in these Bulletins for one year after the declaration of a state of emergency and in effect at the time of the declared emergency, based solely on the fact that the insured structure is located in an area in which a fire has occurred. The Company will comply with these Bulletins and does not believe that these Bulletins will have a material adverse impact on its financial condition or cash flows. Litigation 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 Note 1. Summary of Significant Accounting Policies. The Company also 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. 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. The Company is also involved in proceedings relating to assessments made by the FTB. See Note 11. Income Taxes.
