Accounting Policies [Abstract]
Accounting Policies and Basis of Presentation	Summary of Significant Accounting Policies Accounting Principles - The accompanying consolidated financial statements have been prepared in conformity with the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) of accounting principles generally accepted in the United States of America (GAAP). These interim financial statements should be read in conjunction with these notes and those included in the Company's 2025 Annual Report on Form 10-K incorporated herein by reference. The financial accounting and reporting process relies on estimates and on the exercise of judgment. In the opinion of management all adjustments consisting only of normal recurring accruals necessary for a fair presentation of interim periods' results and financial condition have been recorded. Pertinent accounting and disclosure pronouncements issued by the FASB are adopted by the Company as they become effective. Statement Presentation - Amounts shown in the consolidated financial statements and applicable notes are stated (except as otherwise indicated and as to per share data) in millions, which amounts may not add to totals shown due to truncation. Prior period amounts have been reclassified whenever appropriate to conform to the most current presentation. Accounting Standards Pending Adoption - In November 2024, the FASB issued ASU No. 2024-03, Disaggregation of Income Statement Expenses which will require additional disclosure as to the nature of expenses included in the income statement. The new standard requires disclosures about specific types of expenses included in the expense captions presented on the face of the income statement, such as employee compensation, depreciation, and intangible asset amortization. The guidance does not change the requirements for the presentation of expenses on the face of the income statement. The requirements are effective for fiscal years beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027 and will be applied prospectively with the option for retrospective application. The Company is currently evaluating the impact of this disclosure-only guidance. In September 2025, the FASB issued ASU No. 2025-06, Targeted Improvements to the Accounting for Internal-Use Software which clarifies and modernizes accounting for costs related to internal-use software to better align with current software development practices, including agile methodologies. The new standard removes all references to software development project stages, clarifies threshold requirements to begin capitalizing costs, and provides guidance on how to evaluate whether the probable-to-complete threshold has been met. Under this new guidance, an entity will be required to capitalize software costs when both: •Management, with the relevant authority, implicitly or explicitly authorizes and commits to funding a computer software project, and •It is probable that the project will be completed and the software will be used to perform the function intended. The requirements are effective for interim and annual periods in fiscal years beginning after December 15, 2027, and can be applied on a prospective, modified, or retrospective transition approach. The Company is currently evaluating the impact of this guidance. Investments - The Company classifies its fixed income securities as those it either (1) has the intent and ability to hold until maturity, (2) has available for sale, or (3) has the intention of trading. The Company's fixed income portfolio is classified as available for sale as of June 30, 2026 and December 31, 2025. Investment income is reported net of allocated expenses and includes appropriate adjustments for amortization of premium and accretion of discount on fixed income securities acquired at other than par value. Dividends on equity securities are credited to income on the ex-dividend date. At June 30, 2026, the Company and its subsidiaries do not have significant amounts of non-income producing securities. Revenue Recognition - Most Specialty Insurance premiums pertain to annual policies and are reflected in income on a pro-rata basis in association with the related loss and loss adjustment expenses. Auto warranty policy premiums are often earned over several years with earning patterns correlated to anticipated paid claim activity. Title Insurance premium and fee revenues stemming from the Company's direct operations (which include branch offices of its title insurers and wholly-owned agency subsidiaries) are generally recognized as income at the transaction closing date which approximates the policy effective date. Fee income related to escrow and other closing services is recognized when the related services have been performed and completed. The remaining Title Insurance premium and fee revenues are produced by independent title agents. Rather than making estimates that could be subject to significant variance from actual premium and fee production, the Company recognizes revenues from those sources upon receipt. Such receipts can result in up to a four-month lag relative to the effective date of the underlying title policy, and are offset concurrently by production expenses and loss reserve provisions. Loss and Loss Adjustment Expense Reserves - The establishment of loss reserves is a reasonably complex and dynamic process influenced by a large variety of factors. The Company's accounting policy regarding the establishment of loss reserve estimates is described in Note 1 in the Notes to Consolidated Financial Statements included in Old Republic's 2025 Annual Report on Form 10-K. Reinsurance - The cost of reinsurance is recognized over the terms of the reinsurance contracts. Amounts recoverable from reinsurers for loss and loss adjustment expenses are estimated in a manner consistent with the claim liability associated with the reinsured business. The Company evaluates the financial condition of its reinsurers on a regular basis, and allowances are established for estimated credit losses. Common Share Repurchases - Common shares acquired under share repurchase programs are generally retired, restoring them to authorized, unissued status. Repurchases above par value are first charged to additional paid-in capital, with any excess charged to retained earnings.
