Accounting Policies [Abstract]
Management's responsibility	Management’s responsibility. The accompanying interim financial statements were prepared by management, who is responsible for their integrity and objectivity. These financial statements have been prepared in conformity with the United States (U.S.) generally accepted accounting principles (GAAP), including management’s best judgments and estimates. In the opinion of management, all adjustments necessary for a fair presentation of this information for all interim periods, consisting only of normal recurring accruals, have been made. The Company’s results of operations for interim periods are not necessarily indicative of results for a full year and actual results could differ.
Consolidation	Consolidation. The condensed consolidated financial statements include all subsidiaries in which the Company owns more than 50% voting rights in electing directors. All significant intercompany amounts and transactions have been eliminated and provisions have been made for noncontrolling interests. Unconsolidated investees, in which the Company typically owns from 20% through 50% of the voting stock, are accounted for using the equity method.
Restrictions on cash and investments	Restrictions on cash and investments. The Company maintains investments in accordance with certain statutory requirements for the funding of statutory premium reserves. Statutory reserve funds are required to be fully funded and invested in high-quality securities and short-term investments. Statutory reserve funds are not available for current claim payments, which must be funded from current operating cash flow. Included in investments in debt and equity securities are statutory reserve funds of approximately $497.5 million and $483.4 million at March 31, 2020 and December 31, 2019, respectively. In addition, included within cash and cash equivalents are statutory reserve funds of approximately $18.3 million and $39.7 million at March 31, 2020 and December 31, 2019, respectively. Although these cash statutory reserve funds are not restricted or segregated in depository accounts, they are required to be held pursuant to state statutes. If the Company fails to maintain minimum investments or cash and cash equivalents sufficient to meet statutory requirements, the Company may be subject to fines or other penalties, including potential revocation of its business license. These funds are not available for any other purpose. In the event that insurance regulators adjust the determination of the statutory premium reserves of the Company’s title insurers, these restricted funds as well as statutory surplus would correspondingly increase or decrease.
Recently adopted accounting standard and Recent accounting standard not yet adopted	Recently adopted accounting standard. In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (Topic 326). Topic 326 significantly changed the impairment model for financial instruments by introducing the current expected credit loss (CECL) model, which requires the immediate recognition of estimated credit losses expected to occur over the remaining life of the financial instrument. The previous GAAP generally required the recognition of credit losses when incurred. Topic 326 also amended certain accounting treatments for available-for-sale debt securities. Effective January 1, 2020, the Company adopted Topic 326 which did not result in any material impact on its consolidated financial statements.
