Aflac Incorporated sells supplemental health and life insurance designed to pay cash benefits directly to policyholders when covered events occur, helping households manage out-of-pocket medical and income-disruption costs. The company operates through two core reporting segments—Aflac Japan and Aflac U.S.—and serves millions of policyholders in Japan and the United States. In the U.S., distribution is built around worksite/employee-benefits channels supported by a large agent and broker force, while Japan is centered on long-duration health and life products. Earnings and capital generation are tightly linked to underwriting performance (morbidity, mortality, persistency) and to investment portfolio results, including interest rates, credit spreads, and hedging outcomes.
