Aflac Incorporated is a leading global provider of supplemental health and life insurance products, operating primarily in the United States and Japan. The company's business model focuses on providing financial protection against out-of-pocket medical expenses not covered by primary health insurance, paying cash benefits directly to policyholders when they experience a covered accident or illness. Aflac operates through two main segments: Aflac Japan and Aflac U.S. The Aflac Japan segment is the company's largest revenue contributor, offering cancer, medical, nursing care, and whole life insurance products, and distributing through a vast network of agencies and banks, including Japan Post. The Aflac U.S. segment provides accident, disability, critical illness, hospital indemnity, dental, vision, and life insurance, primarily distributed through worksite payroll deductions, independent associates, and brokers. Aflac is highly distinctive for its strong brand recognition, bolstered by the iconic Aflac Duck advertising campaign, and its dominant market position in supplemental coverage in both of its core geographic markets.
