INFORMATION CONCERNING FORWARD-LOOKING STATEMENTS 
This report and reports we will subsequently file or furnish and have previously filed or furnished with the United States Securities and Exchange Commission (“SEC”) contain certain statements related to future results, or state our intentions, beliefs and expectations or predictions for the future, which are forward-looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995. Forward-looking statements relate to expectations or forecasts of future events. They are typically identified by words such as “anticipate,” “believe,” “estimate,” “expect,” “forecast,” “project,” “intend,” “plan,” “probably,” “potential,” “looking forward,” “continue,” and other similar terms, and future or conditional tense verbs like “could,” “may,” “might,” “should,” “will,” and “would.” You can also identify forward-looking statements by the fact that they do not relate strictly to historical or current facts. For example, we may use forward-looking statements when addressing topics such as: market and industry conditions, including competitive and pricing trends; public health concerns and continuing uncertainty in connection with COVID-19; changes in our business strategies and methods of generating revenue; the development and performance of our services and products; changes in the composition or level of our revenues; our cost structure and the outcome of cost-saving or restructuring initiatives; the outcome of contingencies; dividend policy; the expected impact of acquisitions and dispositions; pension obligations; cash flow and liquidity; expected effective tax rate; future actions by regulators; risks related to the Combination; and the impact of changes in accounting rules. Forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from either historical or anticipated results depending on a variety of factors. Potential factors, which may be revised or supplemented in subsequent reports filed or furnished with the SEC, that could impact results include:
general economic and political conditions in the countries in which we do business around the world, including the withdrawal of the United Kingdom (the “U.K.”) from the European Union;
changes in the competitive environment or damage to our reputation;
fluctuations in exchange and interest rates that could influence revenues and expenses;
changes in global equity and fixed income markets that could affect the return on invested assets;
changes in the funding status of our various defined benefit pension plans and the impact of any increased pension funding resulting from those changes;
the level of our debt limiting financial flexibility or increasing borrowing costs;
rating agency actions that could affect our ability to borrow funds;
volatility in our tax rate due to a variety of different factors including the United States (the “U.S.”) federal income tax reform;
changes in estimates or assumptions on our financial statements;
limits on our subsidiaries to make dividend and other payments to us;
the impact of lawsuits and other contingent liabilities and loss contingencies arising from errors and omissions and other claims against us;
the impact of, and potential challenges in complying with, legislation and regulation in the jurisdictions in which we operate, particularly given the global scope of our businesses and the possibility of conflicting regulatory requirements across jurisdictions in which we do business;
the impact of any investigations brought by regulatory authorities in Ireland, the U.S., U.K., and other countries;
the impact of any inquiries relating to compliance with the U.S. Foreign Corrupt Practices Act and non-U.S. anti-corruption laws and with U.S. and non-U.S. trade sanctions regimes;
failure to protect intellectual property rights or allegations that we infringe on the intellectual property rights of others;
the effects of Irish law on our operating flexibility and the enforcement of judgments against us;
the failure to retain and attract qualified personnel;
international risks associated with our global operations;
the effects of natural or man-made disasters, including the effects of COVID-19 and other health pandemics;



the potential of a system or network breach or disruption resulting in operational interruption or improper disclosure of personal data;
our ability to develop and implement new technology;
damage to our reputation among clients, markets or third parties;
the actions taken by third parties that perform aspects of our business operations and client services;
the extent to which we manage certain risks created in connection with the various services, including fiduciary and investment consulting and other advisory services, among others, that we currently provide, or will provide in the future, to clients;
our ability to continue, and the costs and risks associated with, growing, developing and integrating companies that we acquire or new lines of business;
changes in commercial property and casualty markets, commercial premium rates or methods of compensation;
changes in the health care system or our relationships with insurance carriers;
our ability to implement initiatives intended to yield cost savings and the ability to achieve those cost savings;
risks and uncertainties associated with the sale of the Divested Business, as defined in Note 6 “Restructuring”;
our ability to realize the expected benefits from our restructuring plan; and
risks and uncertainties associated with the Combination, as defined in Note 7 “Acquisitions and Dispositions of Businesses”, including our ability to obtain the requisite approvals of, to satisfy the other conditions to, or to otherwise complete, the Combination on the expected time frame, or at all, the occurrence of unanticipated difficulties or costs in connection with the Combination, our ability to successfully integrate the combined companies following the Combination and our ability to realize the expected benefits from the Combination.

Any or all of our forward-looking statements may turn out to be inaccurate, and there are no guarantees about our performance.

Notes to Condensed Consolidated Financial Statements (Unaudited)
1. Basis of Presentation
The accompanying unaudited Condensed Consolidated Financial Statements and Notes thereto (the “Financial Statements”) have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). The Financial Statements include the accounts of Aon plc, an Irish public limited company, and all of its controlled subsidiaries. Intercompany accounts and transactions have been eliminated. The Financial Statements include, in the opinion of management, all adjustments (consisting of normal recurring adjustments and reclassifications) necessary to present fairly the Company’s consolidated financial position, results of operations, and cash flows for all periods presented.
Certain information and disclosures normally included in the Financial Statements prepared in accordance with U.S. GAAP have been condensed or omitted. The Financial Statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, including amendments and additions disclosed on Form 8-K issued April 1, 2020. The results for the three and nine months ended September 30, 2020 are not necessarily indicative of operating results that may be expected for the full year ending December 31, 2020, particularly in light of the continuing effect of the COVID-19 pandemic.
On April 1, 2020, a scheme of arrangement under English law was completed pursuant to which the Class A ordinary shares of Aon plc, a public limited company incorporated under the laws of England and Wales and the publicly traded parent company of the Aon group (“Aon Global Limited”), were cancelled and the holders thereof received, on a one-for-one basis, Class A ordinary shares of Aon plc, an Irish public limited company formerly known as Aon Limited (“Aon plc”), as described in the proxy statement filed with SEC on December 20, 2019 (the “Ireland Reorganization”). Aon plc is a tax resident of Ireland. References in this report to “Aon,” the “Company,” “we,” “us,” or “our” for time periods prior to April 1, 2020 refer to Aon Global Limited. References in the Financial Statements to “Aon,” the “Company,” “we,” “us,” or “our” for time periods on or after April 1, 2020, refer to Aon plc.
Use of Estimates
The preparation of the Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities at the date of the Financial Statements, and the reported amounts of reserves and expenses. These estimates and assumptions are based on management’s best estimates and judgments. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment. Management believes its estimates to be reasonable given the current facts available. Aon adjusts such estimates and assumptions when facts and circumstances dictate. Illiquid credit markets, volatile equity markets, foreign currency exchange rate movements, and, recently, impacts from the COVID-19 pandemic increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in estimates resulting from continuing changes in the economic environment would, if applicable, be reflected in the Financial Statements in future periods.
2. Accounting Principles and Practices
Adoption of New Accounting Standards
Cloud Computing Arrangements
In August 2018, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance on implementation costs incurred in a cloud computing arrangement that is a service contract. The new guidance aligns capitalization requirements for certain implementation costs incurred in cloud computing arrangements with existing requirements for capitalizing implementation costs for internal-use software. These costs will be deferred over the term of the hosting arrangement, including any optional renewal periods the entity is reasonably certain to exercise. An entity may apply the new guidance on either a prospective or retrospective basis. The new guidance was effective for Aon in the first quarter of 2020 and was adopted on a prospective basis for all implementation costs incurred after the date of initial adoption. The adoption of this guidance had no significant impact on the Financial Statements.
Simplifying the Test for Goodwill Impairment
In January 2017, the FASB issued new accounting guidance on simplifying the test for goodwill impairment. Currently the standard requires an entity to perform a two-step test to determine the amount, if any, of goodwill impairment. In Step 1, an entity compares the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of the reporting unit exceeds its fair value, the entity performs Step 2 and compares the implied fair value of goodwill with the carrying amount of that goodwill for that reporting unit. An impairment charge equal to the amount by which the carrying
12


amount of goodwill for the reporting unit exceeds the implied fair value of that goodwill is recorded, limited to the amount of goodwill allocated to that reporting unit. The new guidance removes Step 2. An entity will apply a one-step quantitative test and record the amount of goodwill impairment as the excess of a reporting unit’s carrying amount over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. The new guidance does not amend the optional qualitative assessment of goodwill impairment. The new guidance was effective for Aon in the first quarter of 2020 and was adopted on a prospective basis. The adoption of this guidance had no impact on the Financial Statements.
Credit Losses
In June 2016, the FASB issued a new accounting standard on the measurement of credit losses on financial instruments. The new standard replaces the current incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The Company adopted the new standard as of January 1, 2020 using the modified retrospective approach. Under this approach, prior periods were not restated. Rather, the cumulative effect of initially applying the new standard was recognized as an adjustment to retained earnings. Upon the adoption of this guidance on January 1, 2020, the Company recognized a cumulative adjustment of $6 million to decrease retained earnings.
The Company’s estimate for allowance for credit losses with respect to receivables is based on a combination of factors, including evaluation of forward-looking information, historical write-offs, aging of balances, and other qualitative and quantitative analyses.
Financial Disclosures about Guarantors
In March 2020, the SEC issued a final rule that amended the disclosure requirements related to certain registered securities under SEC Regulation S-X Rules 3-10 and 3-16 of Regulation S-X. The changes are intended to provide investors with material information given the specific facts and circumstances, make disclosures easier to understand, and reduce the cost and burdens to registrants. The final rule replaces the requirement to provide condensed consolidated financial information with a requirement to present summarized financial information of the issuers and guarantors in the registrant’s Management Discussion and Analysis section or in the financial statements and reduces the periods for which summarized financial information is presented to the most recent annual period and year-to-date interim period. The amendments are effective January 4, 2021, with early adoption permitted.
The Company elected to early adopt the final rule in the second quarter of 2020 and elected to present these disclosures in Item 2, Management’s Discussion and Analysis of Financial Condition and Results of Operations.
Accounting Standards Issued But Not Yet Adopted
Simplifying the Accounting for Income Taxes
In December 2019, the FASB issued new accounting guidance that simplifies the accounting for income taxes by removing certain exceptions to the general principles in the existing guidance. It also clarifies certain aspects of the existing guidance to promote more consistent application. The new guidance is effective for Aon in the first quarter of 2021, with early adoption permitted. The Company previously expected to adopt this guidance in the first quarter of 2021 and is now considering early adoption in the fourth quarter of 2020. Different components of the guidance require retrospective, modified retrospective, or prospective adoption. The Company does not expect there to be a significant impact on the Financial Statements.
Changes to the Disclosure Requirements for Defined Benefit Plans
In August 2018, the FASB issued new accounting guidance related to the disclosure requirements for employers that sponsor defined benefit pension and other postretirement benefit plans. The guidance requires sponsors of these plans to provide additional disclosures, including weighted average interest rates used in the entity’s cash balance pension plans and a narrative description of reasons for any significant gains or losses impacting the benefit obligation for the period, and eliminates certain previous disclosure requirements. The new guidance is effective for Aon in the first quarter of 2021 and will be applied retrospectively in the Notes to Condensed Consolidated Financial Statements.
