Commitments and Contingencies Disclosure [Abstract]
Contingencies and Other Matters	Note 24 – Contingencies and Other Matters The Company, through its subsidiaries, is contingently liable for various guarantees provided in the ordinary course of business. A.Financial Guarantees: Retiree and Life Insurance Benefits The 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. As of December 31, 2023, employers maintained assets that generally exceeded the benefit obligations under these arrangements of approximately $420 million. An additional liability is established if management believes that the Company will be required to make payments under the guarantees; there were no additional liabilities required for these guarantees, net of reinsurance, as of December 31, 2023. Separate account assets supporting these guarantees are classified in Levels 1 and 2 of the GAAP fair value hierarchy. The Company does not expect that these financial guarantees will have a material effect on the Company's consolidated results of operations, liquidity or financial condition. B.Certain Other Guarantees The Company had indemnification obligations as of December 31, 2023 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. There were no liabilities for these indemnification obligations as of December 31, 2023. C.Guaranty Fund Assessments The Company operates in a regulatory environment that may require its participation in assessments under state insurance guaranty association laws. The Company's exposure to assessments for certain obligations of insolvent insurance companies to policyholders and claimants is based on its share of business written in the relevant jurisdictions. There were no material charges or credits resulting from existing or new guaranty fund assessments for the year ended December 31, 2023. Legal and Regulatory Matters The Company is routinely involved in numerous claims, lawsuits, regulatory inquiries and audits, government investigations, including under the federal False Claims Act and state false claims acts initiated by a government investigating body or by a qui tam relator's filing of a complaint under court seal, and other legal matters arising, for the most part, in the ordinary course of managing a global health company. Additionally, the Company has received and is cooperating with subpoenas or similar processes from various governmental agencies requesting information, all arising in the normal course of its business. Disputed tax matters arising from audits by the Internal Revenue Service or other state and foreign jurisdictions, including those resulting in litigation, are accounted for under GAAP guidance for uncertain tax positions, as described in Note 23. Pending litigation and legal or regulatory matters that the Company has identified with a reasonably possible material loss and certain other material litigation matters are described below. For those matters that the Company has identified with a reasonably possible material loss, the Company provides disclosure in the aggregate of accruals and range of loss, or a statement that such information cannot be estimated. The Company's accrual for the matter discussed below under "Litigation Matters" is not material. Due to numerous uncertain factors presented in this case, it is not possible to estimate an aggregate range of loss (if any) for this matter at this time. In light of the uncertainties involved in this matter, there is no assurance that its ultimate resolution will not exceed the amount currently accrued by the Company. An adverse outcome in this matter could be material to the Company's results of operations, financial condition or liquidity for any particular period. The outcomes of lawsuits are inherently unpredictable and we may be unsuccessful in this ongoing litigation matter or any future claims or litigation. Litigation Matters Express Scripts Litigation with Elevance. In March 2016, Elevance filed a lawsuit in the United States District Court for the Southern District of New York alleging various breach of contract claims against Express Scripts relating to the parties' rights and obligations under the periodic pricing review section of the pharmacy benefit management agreement between the parties including allegations that Express Scripts failed to negotiate new pricing concessions in good faith, as well as various alleged service issues. Elevance also requested that the court enter declaratory judgment that Express Scripts is required to provide Elevance competitive benchmark pricing, that Elevance can terminate the agreement and that Express Scripts is required to provide Elevance with post-termination services at competitive benchmark pricing for one year following any termination by Elevance. Elevance claimed it is entitled to $13 billion in additional pricing concessions over the remaining term of the agreement, as well as $1.8 billion for one year following any contract termination by Elevance and $150 million damages for service issues ("Elevance's Allegations"). On April 19, 2016, in response to Elevance's complaint, Express Scripts filed its answer denying Elevance's Allegations in their entirety and asserting affirmative defenses and counterclaims against Elevance. The court subsequently granted Elevance's motion to dismiss two of six counts of Express Scripts' amended counterclaims. Express Scripts filed its Motion for Summary Judgment on August 27, 2021. Elevance completed filing of its Response to Express Scripts' Motion for Summary Judgment on October 16, 2021. Express Scripts filed its Reply in Support of its Motion for Summary Judgment on November 19, 2021. On March 31, 2022, the court granted summary judgment in favor of Express Scripts on all of Elevance's pricing claims for damages totaling $14.8 billion and on most of Elevance's claims relating to service issues. Elevance's only remaining service claims relate to the review or processing of prior authorizations, with alleged damages over $100 million. On November 1, 2023, the parties signed a settlement agreement pursuant to which Express Scripts agreed to resolve the service-related claims. The settlement agreement is not an admission of liability or fault by Express Scripts, the Company or its subsidiaries. Following the settlement, Elevance retains the right to appeal the pricing-related claims that were previously dismissed by the court and Express Scripts retains the ability to reassert its own pricing-related claims in the event any appeal by Elevance is successful. Elevance filed its Notice of Appeal of its pricing-related claims on December 12, 2023. Elevance’s opening appellate brief is due March 25, 2024.
