Aflac, Inc. (American Family Life Assurance Company) is an American insurance company headquartered in Columbus, Georgia. It was founded in 1955 as American Family Life Insurance Company of Columbus by John Amos and his brothers Paul and Bill Amos, who saw a need for financial protection when a medical situation occurs. In 1964, the company changed its name to the American Family Life Assurance Company of Columbus, and in 1989 the company adopted the acronym “Aflac.”
The company does business in two of the largest insurance markets in the world — the United States and Japan — and offers several types of insurance products, including Accident Insurance, Cancer Insurance, Critical Illness Insurance, Life Insurance, Hospital Insurance, Short-Term Disability Insurance, Dental Insurance, and Vision Insurance. With more than 13,000 employees and over 50 million clients worldwide, Aflac is considered one of the largest providers of guaranteed-renewable insurance and one of the largest providers of supplemental insurance in the U.S. It is also one of the largest insurance companies in Japan, when measured by individual insurance policies in force.
According to Fortune Magazine, the company has appeared on Fortune’s America’s Most Admired Companies list as well as the Fortune 500 list of largest United States corporations by revenue. According to Forbes, it is considered one of the top 2,000 largest public companies in the world. Aflac stock trades on the New York Stock Exchange under the ticker symbol AFL.
Aflac Founders
John B. Amos (1924–1990)
A lawyer and entrepreneur from Columbus, Georgia, John was the driving visionary behind the company. He recognized a gap in the market: existing health coverage rarely helped families with the everyday costs of illness — lost income, travel, childcare — and set out to fix it. He served as the company’s first chairman and chief executive. The cancer insurance policy he championed, introduced in 1958, became Aflac’s defining product for decades.
Paul S. Amos (1930–2014)
Paul was the sales architect of the family business. He developed the “cluster selling” technique in the early 1960s, a method of selling supplemental insurance to groups of employees at the same workplace rather than door to door. This approach, introduced commercially in 1964, dramatically lifted premium income and became the blueprint for how Aflac sells its products to this day — primarily through payroll deduction at the worksite.
William (Bill) Amos
The third brother and co-founder, Bill handled operations and administration during the company’s early years, allowing John and Paul to focus on strategy and sales. Together the three brothers built a company from a six-room office with 16 employees and 60 agents into a national and eventually international insurance force — all around the idea that when illness strikes, your insurance should pay you, not just your doctor.
Insurance Products
Accident Insurance
Pays cash benefits for covered injuries resulting from accidents, regardless of other coverage the policyholder holds.
Cancer Insurance
Aflac’s original and flagship product. Provides cash payments for diagnosis and treatment of cancer, paying directly to the insured rather than to providers.
Critical Illness Insurance
A lump-sum cash benefit paid upon diagnosis of a covered condition such as heart attack, stroke, or organ failure.
Life Insurance
Term and whole life policies offered primarily in the United States and Japan, including WAYS and child endowment plans in the Japanese market.
Hospital Insurance
Pays benefits for confinement in a hospital, covering costs that major medical insurance typically leaves to the patient.
Short-Term Disability
Replaces a portion of income when a policyholder is unable to work due to a covered illness or injury, sold primarily through employers at the worksite.
Dental & Vision Insurance
Group and individual dental and vision plans, administered through Aflac Benefit Solutions (formerly Argus Dental and Vision) and SKYGEN USA.
Nursing & Care (Japan)
Products specific to the Japanese market, including dementia care and nursing care policies. Aflac Japan introduced the world’s first dementia care insurance policy in 1984.
Aflac History
1955
On November 17, John, Paul, and Bill Amos establish American Family Life Insurance Company of Columbus in Columbus, Georgia. The company opens in a six-room office with 16 employees and 60 agents. Their original model involves door-to-door sales of life, health, and accident insurance — but the brothers quickly identify a more pressing unmet need around catastrophic medical costs.
1958
Aflac introduces cancer insurance, becoming one of the first companies in the United States to offer a standalone policy specifically for cancer diagnosis and treatment. The policy pays cash directly to the insured, not to the hospital or doctor. The product becomes the company’s defining offering for the next several decades and anchors its identity around financial protection during serious illness.
1964
The company adopts a new name — American Family Life Assurance Company of Columbus — and Paul Amos rolls out the “cluster selling” technique, selling supplemental insurance to groups of employees at their workplace rather than one household at a time. The approach produces immediate results; annual premiums reach $7 million by 1967. Worksite distribution through payroll deduction becomes the foundation of Aflac’s business model.
1970–1974
By 1970, Aflac is licensed in 37 states, graduating from a regional insurer to a national one. In 1974 Aflac enters the Japanese market, introducing its cancer insurance products to Japanese consumers. The entry proves prescient: Japan’s national health system covers hospitalization but leaves patients exposed on the cost of actual cancer treatment, creating a natural market for supplemental cancer coverage. Aflac dominates Japanese cancer insurance for eight consecutive years.
1984
Aflac Japan introduces the world’s first dementia care insurance policy, becoming a pioneer in covering an illness that most insurers were not yet treating as a distinct risk category. The move reflects an early understanding of Japan’s aging population and the long-term financial burdens that dementia places on families — a product category that becomes increasingly important to the Japanese market in subsequent decades.
1989
The company officially adopts the acronym “Aflac,” which had long been used informally in advertising and by customers. The name change streamlines the brand and sets the stage for broader marketing efforts in the following decade. The acronym had already proven to be highly memorable — a quality that an advertising agency would exploit to remarkable effect eleven years later.
1990–1995
John B. Amos, the company’s founding chairman, passes away in 1990. His nephew Daniel P. Amos assumes the role of chief executive officer, beginning a leadership tenure that continues to this day and makes him one of the longest-serving CEOs of a major U.S. public company. In 1995, the company officially changes its name to Aflac Incorporated and lists on the New York Stock Exchange under the ticker AFL, giving it access to capital markets for the first time.
1999–2000
Aflac launches its now-iconic duck advertising campaign in the United States in December 1999. The duck, created by Kaplan Thaler Group after an art director noticed how closely “Aflac” sounds like a duck’s quack, transforms a large but relatively obscure insurance company into a household name. Brand recognition in the U.S. rises from around 12% to over 90% within a few years. The campaign becomes one of the most successful insurance advertising efforts in American history.
2005
Aflac announces a landmark distribution partnership with Japan Post, the country’s dominant postal and financial services network. Japan Post’s vast network of post offices — numbering in the tens of thousands — gives Aflac access to distribution channels that independent agencies could never replicate. The partnership substantially broadens Aflac Japan’s reach beyond the corporate worksite market and helps solidify its position as Japan’s largest insurance company by individual policies in force.
2009
Aflac acquires Continental American Insurance Company (CAIC) for $100 million. Originally founded in 1980 as Carolina Continental Insurance Company in Columbia, South Carolina, CAIC specializes in voluntary group insurance products sold through brokers at the worksite. The acquisition allows Aflac to offer its supplemental products on both individual and group platforms — a meaningful expansion of its market reach within the employer benefits space.
2011
Following the Tōhoku earthquake and tsunami in March 2011, Aflac donates $5 million to Japanese relief efforts and accelerates payments to affected policyholders in Japan. The disaster tests the company’s operational resilience in its largest market. Comedian Gilbert Gottfried, the voice of the Aflac duck in the U.S. since 2000, is dismissed after posting insensitive tweets about the disaster. Daniel McKeague becomes the new duck voice in May 2011.
2017–2018
Aflac acquires Empowered Benefits, LLC in March 2017, a benefits administration and enrollment software company that strengthens Aflac’s digital capabilities in the employer market. In 2018, Aflac introduces the My Special Aflac Duck — a social robot designed to provide comfort and distraction to children undergoing cancer treatment. The robot, developed in partnership with robotics firm Sproutel, earns widespread media attention and CES Innovation Awards.
2024
Aflac marks 50 years of operations in Japan and 50 years listed on the New York Stock Exchange. Annual revenue reaches $18.9 billion, a slight increase from 2023 despite ongoing headwinds from the weak Japanese yen, which depresses the dollar value of Aflac Japan’s earnings when translated. The company has paid a quarterly dividend without interruption for more than 40 years and remains one of the Dividend Aristocrats on the S&P 500.
Aflac Revenue
Reported in USD billion, calendar year ending December 31. The decline from 2021 onward largely reflects the weakening of the Japanese yen against the U.S. dollar, which reduces the reported dollar value of Aflac Japan’s yen-denominated revenues; Aflac Japan still represents the majority of earnings on a local-currency basis.
Aflac Acquisitions
Aflac’s acquisition history is short by the standards of large insurance companies, which reflects a business built primarily on organic growth in two markets it entered early and has defended over decades. The company’s core strategy has been product innovation and distribution expansion rather than deal-making. That said, the transactions it has done are precise and purposeful.
The most consequential acquisition was Continental American Insurance Company (CAIC) in October 2009, purchased for $100 million. CAIC was a Columbia, South Carolina-based provider of voluntary group insurance products distributed by brokers at the worksite — a channel Aflac had historically not served well with its individual-first sales model. By absorbing CAIC, Aflac gained the ability to sell supplemental coverage through the broker channel to employer groups, not just to individual employees through its own agent force. CAIC now operates as the group platform for Aflac, underwriting group accident, disability, life, and critical illness policies marketed under the Continental American Insurance Company and Aflac Group names.
In March 2017 Aflac acquired Empowered Benefits, LLC, a benefits administration and technology company focused on digital enrollment at the worksite. As employers moved benefits enrollment online and onto mobile devices, Aflac needed software infrastructure to compete with carriers who had invested heavily in digital platforms. Empowered Benefits became part of what Aflac now calls Aflac Benefit Solutions. The same division absorbed Argus Dental and Vision — a dental and vision benefits administrator Aflac acquired to support its dental and vision product lines — which was rebranded as Aflac Benefit Solutions.
Beyond those primary acquisitions, Aflac launched Aflac Ventures, a $100 million venture fund to invest in early-stage insurance technology and digital health startups, reflecting the company’s recognition that its next phase of growth requires digital distribution and claims automation as much as any traditional product or market expansion.
Aflac Market Cap
Approximate year-end market capitalizations (USD billion). The 2022–2023 appreciation reflects strong profitability, rising U.S. interest rates that benefited Aflac’s investment portfolio, and consistent shareholder returns through dividends and buybacks.
Aflac Competitors
In the U.S. supplemental insurance market, Aflac’s most direct rivals are Unum Group and its Colonial Life subsidiary, which mirror Aflac’s worksite distribution model almost exactly. MetLife competes across accident, critical illness, and hospital indemnity lines while also holding a substantial position in dental and vision — the same segments Aflac has been building. Cigna and Prudential Financial compete on broader group benefits platforms. In Japan, the competitive environment includes Nippon Life, Dai-ichi Life, and MS&AD Insurance Group, all of which offer cancer and medical insurance products in Aflac’s core category.

FAQs
What does Aflac actually do?
Aflac sells supplemental insurance — policies that pay cash benefits directly to the policyholder when a covered medical event occurs, rather than paying hospitals or doctors. The cash can be used for anything: medical bills, mortgage payments, groceries, or childcare while recovering. Because standard health insurance often leaves patients with out-of-pocket costs, deductibles, and lost income, Aflac’s products fill that gap. Most policies are sold through the workplace, where premiums are deducted from paychecks. Aflac operates primarily in the United States and Japan.
Why is Aflac so big in Japan?
Aflac entered Japan in 1974 with cancer insurance at a time when Japan’s national health system did not adequately cover the costs of cancer treatment, particularly the portion left to patients after national coverage. Aflac essentially created the modern cancer insurance market in Japan and dominated it for eight years without a domestic competitor. By the time the Japanese market deregulated and local insurers could offer cancer policies, Aflac had established deep brand recognition and an extensive distribution network through Japan Post and corporate payrolls. Japan still generates the majority of Aflac’s operating earnings, even though it represents a smaller share of reported revenue in USD terms due to yen exchange rate fluctuations.
Who founded Aflac and when?
Aflac was founded on November 17, 1955, in Columbus, Georgia by three brothers: John Amos, Paul Amos, and Bill Amos. John provided the entrepreneurial vision and legal expertise; Paul developed the cluster-selling technique that defined the company’s distribution model; and Bill managed operations. The company was originally called American Family Life Insurance Company of Columbus. It changed its name to American Family Life Assurance Company of Columbus in 1964 and officially adopted the Aflac acronym in 1989.
Who are Aflac’s main competitors?
Unum Group and its Colonial Life subsidiary are Aflac’s most direct competitors in U.S. worksite voluntary benefits. MetLife competes across supplemental accident, critical illness, and dental lines. Cigna and Prudential Financial compete on broader group benefits platforms. In Japan, the primary competitors are Nippon Life, Dai-ichi Life, and MS&AD Insurance Group, all of which have built out cancer and medical insurance offerings since Japan’s insurance market deregulated.
What is the Aflac Duck?
The Aflac Duck is the company’s advertising mascot, introduced in a U.S. television campaign in December 1999. The concept came from a Kaplan Thaler Group art director who noticed that the company’s name sounds like a duck’s quack when spoken aloud. The campaign was designed to solve a specific problem: Aflac was one of the largest insurance companies in the United States and Japan, but most Americans had never heard of it. Within a few years of the duck’s introduction, U.S. brand recognition rose from roughly 12% to over 90%. The duck has since been extended to Japan and has appeared in hundreds of commercials. The original U.S. duck voice was provided by comedian Gilbert Gottfried from 2000 until 2011, and by Daniel McKeague thereafter.
