Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENT LIABILITIES	COMMITMENTS AND CONTINGENT LIABILITIES The Company is a defendant in various lawsuits and receives various regulatory inquiries considered to be in the normal course of business. Members of the Company's senior legal and financial management teams review litigation and regulatory inquiries on a quarterly and annual basis and the Company updates the related estimates, accruals, and disclosures, if any, based on such reviews. For litigation and regulatory matters where it is probable that a loss has been incurred, and the amount of that loss can be reasonably estimated, the Company establishes accruals for loss contingencies. Where a loss may be reasonably possible but not probable, or is probable but not reasonably estimable, no accrual is recorded. The final results of any litigation or regulatory inquiries cannot be predicted with certainty. Although some of this litigation is pending in states where large punitive damages, bearing little relation to the actual damages sustained by plaintiffs, have been awarded in recent years, the Company believes the outcome of pending litigation will not have a material adverse effect on its financial position, results of operations, or cash flows. Cyber Incident On June 12, 2025, the Company identified an incident involving unauthorized access to its network in the U.S. The Company promptly initiated its cybersecurity incident response protocols and believes that it contained the intrusion within hours. The Company’s business remains operational and its systems were not affected by ransomware. The Company continues to serve its policyholders as it responds to this incident and can underwrite policies, review claims, and otherwise service customers as usual. The Company has been conducting a review of potentially impacted individuals and data. The Company is still in the process of validating the extent and nature of the files that were involved and the Company believes that the potential amount of loss cannot be reasonably estimated at this time. Outsourcing Agreements and Other Commitments In May 2025, the Company renewed an outsourcing agreement with an information technology and data services company to provide application maintenance and development services for Aflac Japan. The agreement has a remaining term of three years with an aggregate remaining cost of ¥10.9 billion ($75 million using the June 30, 2025 exchange rate). In February 2025, the Company renewed an outsourcing agreement with an information technology and data services company to provide application maintenance and development services for Aflac Japan. The agreement has a remaining term of three years with an aggregate remaining cost of ¥9.4 billion ($65 million using the June 30, 2025 exchange rate). See Note 3 for details on certain investment commitments. Guaranty Fund Assessments The U.S. insurance industry has a policyholder protection system that is monitored and regulated by state insurance departments. These life and health insurance guaranty associations are state entities (in all 50 states as well as Puerto Rico and the District of Columbia) created to protect policyholders of an insolvent insurance company. All insurance companies (with limited exceptions) licensed to sell life or health insurance in a state must be members of that state’s guaranty association. Under state guaranty association laws, certain insurance companies can be assessed (up to prescribed limits) for certain obligations to the policyholders and claimants of impaired or insolvent insurance companies that write the same line or similar lines of business. Guaranty fund assessments for the three- and six-month periods ended June 30, 2025 and 2024 were immaterial.
