  • Revenues from commission arrangements may fluctuate due to many factors, including cyclical or permanent changes in the insurance and reinsurance markets outside of our control.
  • The profitability of our consulting engagements with clients may not meet our expectations due to unexpected costs, cost overruns, early contract terminations, unrealized assumptions used in our contract bidding process or the inability to maintain our prices.
  • In our investment consulting business, we advise or act on behalf of clients regarding their investments. The results of these investments are uncertain and subject to numerous factors, some of which are within our control and some which are not. Clients that experience losses or lower than expected investment returns may leave us for competitors and/or assert claims against us.
  • The anticipated benefits of the redomiciliation from the U.K. to Ireland may not be realized.
  • We are exposed to fluctuations in currency exchange rates that could negatively impact our financial results and cash flows.
  • Changes in interest rates and deterioration of credit quality could reduce the value of our cash balances and investment portfolios and adversely affect our financial condition or results.
  • Our pension obligations and value of our pension assets could adversely affect our shareholders’ equity, net income, cash flow, and liquidity.
  • We have debt outstanding that could adversely affect our financial flexibility.
  • A decline in the credit ratings of our senior debt and commercial paper may adversely affect our borrowing costs, access to capital, and financial flexibility.
  • Our global effective tax rate is subject to a variety of different factors, which could create volatility in that tax rate, expose us to greater than anticipated tax liabilities or cause us to adjust previously recognized tax assets and liabilities.
  • The global effective tax rate that will apply subsequent to Brexit might become uncertain and may vary from expectations.
  • Changes in our accounting estimates and assumptions could negatively affect our financial position and results of operations.
  • We may be required to record goodwill or other long-lived asset impairment charges, which could result in a significant charge to earnings.
  • We are a holding company and, therefore, may not be able to receive dividends or other payments in needed amounts from our subsidiaries.
  • We are subject to E&O claims against us as well as other contingencies and legal proceedings, some of which, if determined unfavorably to us, could have a material adverse effect on our financial condition or results of operations.
  • Our businesses are subject to extensive governmental regulation, which could reduce our profitability, limit our growth, or subject us to legal and regulatory actions.
  • Failure to protect our intellectual property rights, or allegations that we have infringed on the intellectual property rights of others, could harm our reputation, ability to compete effectively, and financial condition.
  • Our results of operations have been adversely affected and could be materially adversely affected in the future by the COVID-19 global pandemic.
  • The economic and political conditions of the countries and regions in which we operate could have an adverse impact on our business, financial condition, operating results, liquidity, and prospects for growth.
  • Our success depends on our ability to retain, attract and develop experienced and qualified personnel, including our senior management team and other professional personnel.
  • Our global operations expose us to various international risks that could adversely affect our business.
  • The occurrence of natural or man-made disasters could result in declines in business and increases in claims that could adversely affect our financial condition and results of operations.
  • Our inability to successfully recover should we experience a disaster or other business continuity problem could cause material financial loss, loss of human capital, regulatory actions, reputational harm, or legal liability.
  • We rely on third parties to perform key functions of our business operations enabling our provision of services to our clients. These third parties may act in ways that could harm our business.
  • Our business is exposed to risks associated with the handling of client funds.

  • We are subject to various risks and uncertainties in connection with the sale of the Divested Business.
  • We rely on complex information technology systems and networks to operate our business. Any significant system or network disruption due to a breach in the security of our information technology systems could have a negative impact on our reputation, operations, sales, and operating results.
  • Improper disclosure of confidential, personal, or proprietary data could result in regulatory scrutiny, legal liability, or harm to our reputation.
  • Our business performance and growth plans could be negatively affected if we are not able to develop and implement technology-based solutions to support our business operations or if we are not able to effectively drive value for our clients through innovation and technology-based solutions.
  • The Combination is subject to customary closing conditions, including conditions related to regulatory approvals, and may not be completed on a timely basis, or at all, or may be completed on a basis that has a material impact on the value of the combined company.
  • Failure to close the Combination could negatively impact our share price and future business and financial results.
  • While the Combination is pending, we are subject to business uncertainties related to our relationships with employees, clients and suppliers, which could adversely affect our business and operations. These uncertainties could also adversely affect the combined company following the Combination.
  • If completed, the Combination may not achieve its intended results.
  • We and WTW may be unable to successfully integrate their operations. Failure to successfully integrate our and WTW’s businesses in the expected timeframe may adversely affect the future results of the combined company.
  • We have incurred and will incur substantial Combination fees and costs in connection with the Combination.
  • The global effective tax rate that will apply to the combined group subsequent to the Combination is uncertain and may vary from expectations.
  • Litigation filed against WTW and/or Aon could prevent or delay the completion of the transaction or result in the payment of damages following completion of the transaction.
  • We are incorporated in Ireland, and Irish law differs from the laws in effect in the U.S. and may afford less protection to holders of our securities.
  • As an Irish public limited company, certain capital structure decisions regarding the Company will require the approval of shareholders, which may limit the Company’s flexibility to manage its capital structure.
Management Discussion
  • Aon is a leading global professional services firm providing a broad range of risk, retirement, and health solutions underpinned by proprietary data and analytics. Management continues to lead its set of initiatives designed to strengthen Aon and unite the firm with one portfolio of capability enabled by proprietary data and analytics and one operating model to deliver additional insight, connectivity, and efficiency.
  • •Revenue increased $53 million, or 0%, to $11,066 million in 2020 compared to 2019, reflecting 1% organic revenue growth, offset by a 1% unfavorable impact from divestitures, net of acquisitions. Organic revenue growth for the year was driven by strength in the core portions of the business, partially offset by a decline in the more discretionary portions.
  • •Operating expenses decreased $559 million, or 6%, to $8,285 million in 2020 compared to 2019 due primarily to a $451 million decrease in restructuring charges, a $138 million decrease from accelerated amortization related to certain tradenames that were fully amortized in the second quarter, expense discipline in an effort to proactively manage liquidity due to uncertainties surrounding COVID-19 and its impact on the Company, including lower travel and entertainment expense, and a $42 million favorable impact from translating prior year period results at current period foreign exchange rates (“foreign currency translation”), partially offset by $123 million of transaction costs related to the pending combination with WTW and a $37 million increase in expenses related to acquisitions, net of divestitures.
