Aflac Incorporated is the largest provider of supplemental insurance in the United States, founded in 1955 and based in Columbus, Georgia. In the United States, Aflac underwrites a wide range of insurance policies, but is perhaps more known for its payroll deduction insurance coverage, which pays cash benefits when a policyholder has a covered accident or illness. The company states it insures "one of four Japanese households" and is "the largest life insurer in Japan in terms of individual insurance policies in force". Aflac is also well known for its supplemental medical policies.
Aflac currently is the number one supplemental health provider in the U.S., followed closely by Allstate Workplace Division. However, its market share is higher than its next four competitors combined.
In 2009, Aflac acquired Continental American Insurance Company for $100 million this enabled Aflac to sell supplemental insurance on both the individual and group platform.
As of June 30, 2012, Aflac was represented by approximately 19,300 sales agencies in Japan, and 76,900 licensed sales associates in the U.S.
