Commitments and Contingencies Disclosure [Abstract]
Litigation	Litigation As of June 30, 2026, we are not involved in any legal action that we believe could have a material adverse effect on our consolidated financial condition, results of operations, or cash flows. In the ordinary course of conducting business, we are parties in various legal actions. Most matters involve claims litigation handled by our ten insurance subsidiaries (collectively, the "Insurance Subsidiaries") in their capacities as: (i) liability insurers defending or indemnifying third-party claims brought against our customers; (ii) insurers responding to first-party coverage claims; or (iii) liability insurers seeking declaratory judgments regarding coverage obligations. We recognize these matters through unpaid loss and loss expense reserves. Considering potential losses and defense costs reserves, we expect that any potential ultimate liability for ordinary course claims litigation will not be material to our consolidated financial condition, results of operations, or cash flows. From time to time, our Insurance Subsidiaries are named as defendants in other legal actions, including some alleging large or indeterminate amounts. Plaintiffs may style these actions as class actions and seek judicial certification of a state or national class for allegations involving our business practices, including allegations related to medical provider reimbursement under workers compensation or automobile insurance policies, or reimbursement practices involving automobile parts. Similarly, our Insurance Subsidiaries can be named defendants in individual actions seeking extra-contractual damages, punitive damages, or penalties, often alleging bad faith in handling insurance claims. We believe we have valid defenses to these allegations and account for such activity by establishing unpaid loss and loss expense reserves. Considering estimated losses and defense costs reserves, we expect that any potential ultimate liability for these other legal actions will not be material to our consolidated financial condition. Litigation outcomes are inherently unpredictable, and certain matters involve large or indeterminate amounts. Adverse outcomes could materially affect our consolidated results of operations or cash flows in the period in which they occur.
