Commitments and Contingencies Disclosure [Abstract]
Guarantees	Financial Guarantees: Retiree and Life Insurance BenefitsThe Company guarantees that separate account assets will be sufficient to pay certain life insurance or retiree benefits. For the majority of these benefits, the sponsoring employers are primarily responsible for ensuring that assets are sufficient to pay these benefits and are required to maintain assets that exceed a certain percentage of benefit obligations. If employers fail to do so, the Company or an affiliate of the buyer of the retirement benefits business has the right to redirect the management of the related assets to provide for benefit payments.An additional liability is established if management believes that the Company will be required to make payments under the guarantees;Separate account assets supporting these guarantees are classified in Levels 1 and 2 of the GAAP fair value hierarchy.Certain Other GuaranteesThe Company had indemnification obligations as of December 31, 2025 in connection with acquisition and disposition transactions. These indemnification obligations are triggered by the breach of representations or covenants provided by the Company, such as representations for the presentation of financial statements, filing of tax returns, compliance with laws or regulations, or identification of outstanding litigation. These obligations are typically subject to various time limitations, defined by the contract or by operation of law, such as statutes of limitation. In some cases, the maximum potential amount due is subject to contractual limitations based on a stated dollar amount or a percentage of the transaction purchase price, while in other cases limitations are not specified or applicable. The Company does not believe that it is possible to determine the maximum potential amount due under these obligations because not all amounts due under these indemnification obligations are subject to limitation.
Commitment and Contingencies	Accounting Policy. The Company accrues for legal and regulatory matters when a loss contingency is both probable and estimable. The estimated loss is generally recorded in Selling, general and administrative expenses and represents the Company's best estimate of the loss contingency. If the loss estimate is a range, the Company accrues the minimum amount in the range if no amount is better than any other estimated amount in the range. Legal costs to defend the Company's litigation and arbitration matters are expensed as incurred in cases that the Company cannot reasonably estimate the ultimate cost to defend. If the Company can reasonably estimate the cost to defend, a liability for these costs is accrued when the claim is reported.
