Aon plc (English:/ˈeɪɒn/) is a British-American[3]professional services firm. The company operates two divisions: Risk Capital (67% of 2024 revenues), which provides brokerage and consulting services for risk management and insurance and reinsurance, and Human Capital (33% of 2024 revenues), which provides services forhealth insurance,retirement plans,pension plans, and talent advisory.[2]
It is the second largest insurance broker worldwide.[4][5]
The company is ranked 300th on theFortune 500[6] and 388th on theForbes Global 2000.[7]
Founded inChicago byPatrick Ryan, Aon was created in 1982 when the Ryan Insurance Group merged with theCombined Insurance Company of America underW. Clement Stone. In 1987, the holding company was renamed Aon fromaon, aGaelic word meaning "one". The company is globally headquartered inLondon with its North America operations based in Chicago at theAon Center.
W. Clement Stone's mother bought a small Detroit insurance agency, and in 1918 brought her son into the business. Mr. Stone sold low-cost, low-benefit accident insurance, underwriting and issuing policies on-site. The next year he founded his own agency, theCombined Registry Co.[8]
As theGreat Depression began, Stone reduced his workforce and improved training. Forced by his son's respiratory illness to winter in the South, Stone moved toArkansas andTexas. In 1939 he bought American Casualty Insurance Co. of Dallas, Texas. It was consolidated with other purchases as theCombined Insurance Co. of America in 1947. The company continued through the 1950s and 1960s, continuing to sell health and accident policies. In the 1970s, Combined expanded overseas despite being hit hard by the recession.[8]
In 1982, after 10 years of stagnation under Clement Stone Jr., the elder Stone, then 79, resumed control until the completion of amerger withRyan Insurance Co. allowed him to transfer control toPatrick Ryan. Ryan, the son of a Ford dealer in Wisconsin and a graduate ofNorthwestern University, had started his company as an auto credit insurer in 1964. In 1976, the company bought the insurance brokerage units of theEsmark conglomerate. Ryan focused on insurance brokering and added more upscale insurance products. He also trimmed staff and took other cost-cutting measures, and in 1987 he changed Combined's name toAon. In 1992, he bought Dutch insurance brokerHudig-Langeveldt. In 1995, the company sold its remaining direct life insurance holdings toGeneral Electric to focus on consulting.[9]
In June 1995, Aon acquired the Garden City basedtravel insurance firm Berkely Arm, Inc (also known as BerkelyCare Ltd. and The Berkely Group), known for providing travel insurance offerings to cruise lines and tour operators in the United States. This division eventually became known as Aon Affinity Travel Practice.[10]
Aon built a global presence through purchases. In 1997, it bought The Minet Group, as well as the insurance brokerage A&A Services, Inc., founded by Alexander Howden in the late 19th century.[11] It was then that insurance brokerDavid Howden reclaimed the family brand name for the Howden Group.[12] These transactions made Aon (temporarily) the largest insurance broker worldwide. The firm made no US buys in 1998, but doubled its employee base with purchases including Spain's largest retail insurance broker, Gil y Carvajal, and the formation of Aon Korea.[13]
Responding to industry demands, Aon announced its new fee disclosure policy in 1999, and the company reorganised to focus on buying personal line insurance firms and to integrate its acquisitions. That year it bought Nikols Sedgwick Group, an Italian insurance firm, and formed RiskAttack (withZurich US), a risk analysis and financial management concern aimed at technology companies. The cost of integrating its numerous purchases, however, hammered profits in 1999.[14]
Despite its troubles, in 2000 Aon bought Reliance Group's accident and health insurance business, as well as Actuarial Sciences Associates, a compensation and employee benefits consulting company. Later in that year, however, the company decided to cut 6% of its workforce as part of a restructuring effort.[15] In 2003, the company saw revenues increase primarily because of rate hikes in the insurance industry. Also that year, Endurance Specialty, a Bermuda-based underwriting operation that Aon helped to establish in November 2001 along with other investors, went public. The next year Aon sold most of its holdings in Endurance.[16][17]
Aon's New York offices were on the 92nd and 98th–105th floors of theSouth Tower of theWorld Trade Center at the time of theSeptember 11 attacks. When the North Tower was struck byAmerican Airlines Flight 11 at 8:46 a.m., an evacuation of Aon's offices was quickly initiated by executive Eric Eisenberg, and 924 of the estimated 1,100 Aon employees present at the time managed to get below the 77th floor beforeUnited Airlines Flight 175 crashed between Floors 77 and 85 at 9:03 a.m.[18] Many, however, did not manage to get beneath in the 17 minutes they had between the two impacts. As a result, 176 employees of Aon were killed in the crash or died in the eventual collapse of the tower or from smoke inhalation. At 9:59 a.m., the tower collapsed, killing any survivors still within,[19] including Eisenberg andKevin Cosgrove.[20]
In 2004–2005, Aon, along with other brokers includingMarsh & McLennan andWillis, fell under regulatory investigation underNew York Attorney GeneralEliot Spitzer and otherstate attorneys general. At issue was the practice of insurance companies' payments to brokers (known as contingent commissions). The payments were thought to bring a conflict of interest, swaying broker decisions on behalf of carriers, rather than customers. In the spring of 2005, without acknowledging any wrongdoing, Aon agreed to a $190 millionsettlement, payable over 30 months.[21]
In the late 2007, Aon divested its two major underwriting subsidiaries: Combined Insurance Company of America (acquired by ACE Limited for $2.4 billion) and Sterling Life Insurance Company (purchased byMunich Re Group for $352 million) sold due to their low margin and capital-intensive nature.[22][23]
In November 2008, Aon acquired reinsurance intermediary and capital advisor Benfield Group Limited for $1.75 billion. The acquisition amplified the firm's broking capabilities, positioning Aon one of the largest players in the reinsurance brokerage industry.[24]
In 2010, Aon acquired Hewitt Associates for $4.9 billion.[25] Aside from drastically boosting Aon's human resources consulting capacity and entering the firm into the business process outsourcing industry, the move added 23,000 colleagues and more than $3 billion in revenue.[26]

In 2021, Aon agreed to merge withWillis Towers Watson; the merger agreement was terminated due to regulatory concerns.[30][31]
In January 2009, Aon was fined £5.69 million in the UK by the Financial Services Authority, who stated that the fine related to the company's inadequate bribery and corruption controls, claiming that between 14 January 2005 and 30 September 2007 Aon had failed to properly assess the risks involved in its dealings with overseas firms and individuals. The Authority did not find that any money had actually made its way to illegal organisations. Aon qualified for a 30% discount on the fine as a result of its cooperation with the investigation. Aon said its conduct was not deliberate, adding it had since "significantly strengthened and enhanced its controls around the usage of third parties".[32]
In December 2011, Aon Corporation paid a $16.26 million penalty to theU.S. Securities and Exchange Commission and theU.S. Department of Justice for violations of the USForeign Corrupt Practices Act.[33]According to the Securities and Exchange Commission, Aon's subsidiaries made improper payments of over $3.6 million to government officials and third-party facilitators inCosta Rica,Egypt,Vietnam,Indonesia, theUnited Arab Emirates,Myanmar andBangladesh, between 1983 and 2007, to obtain and retain insurance contracts.[34]
