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 and all of its controlled subsidiaries (“Aon” or the “Company”). All 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. These 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, 2017. The results for the three and six months ended June 30, 2018 are not necessarily indicative of operating results that may be expected for the full year ending December 31, 2018.
Use of Estimates
The preparation of the accompanying Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, 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, and foreign currency exchange rate movements 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
Presentation of Net Periodic Pension and Postretirement Benefit Costs
In March 2017, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance on the presentation of net periodic pension cost and net periodic postretirement benefit cost. The new guidance requires that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. It also requires the other components of net periodic pension cost and net periodic postretirement benefit cost to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. Additionally, only the service cost component is eligible for capitalization, when applicable. The Company has applied the new guidance retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the Condensed Consolidated Statement of Income, and prospectively, on and after the effective date, for the capitalization of the service cost component of net periodic pension costs and net periodic postretirement benefit cost in assets. The new guidance allows a practical expedient that permits an employer to use the amounts disclosed in its pension and other postretirement benefit plan note for the prior comparative periods as the estimation basis for applying the retrospective presentation requirements. The Company did not apply the practical expedient upon adoption of this guidance. The new guidance was effective for Aon in the first quarter of 2018. The adoption of this guidance had no impact on the net income of the Company.
7

Upon adoption of the guidance, the presentation of the results reflect a change in Operating income offset by an equal and offsetting change in Other income (expense) for the period ended June 30, 2017 as follows:

|  | Three Months Ended June 30, 2017 |  | Six Months Ended June 30, 2017
|  | As Reported |  | Adjustments |  | As Adjusted |  | As Reported |  | Adjustments |  | As Adjusted
Operating income (loss) (1) |  | $ | (118 | ) |  | $ | (9 | ) |  | $ | (127 | ) |  | $ | 225 |  |  | $ | (17 | ) |  | $ | 208 |
Other income (expense) |  | $ | (5 | ) |  | $ | 9 |  |  | $ | 4 |  |  | $ | (15 | ) |  | $ | 17 |  |  | $ | 2 |

(1) | Reclassification from Operating income is recorded in Compensation and benefits.

Income Tax Consequences of Intercompany Transactions
In October 2016, the FASB issued new accounting guidance on the income tax consequences of intra-entity asset transfers other than inventory. The guidance requires that the seller and buyer recognize the consolidated current and deferred income tax consequences of a transaction in the period the transaction occurs rather than deferring to a future period and recognizing those consequences when the asset has been sold to an outside party or otherwise recovered through use (i.e. depreciated, amortized, or impaired). The Company has applied the new guidance on a modified retrospective basis with a cumulative effect adjustment to retained earnings as of the beginning of the period of adoption. The new guidance was effective for Aon in the first quarter of 2018. Upon the adoption of this guidance on January 1, 2018, the Company recognized an increase to Deferred tax assets of $23 million, an increase to Deferred tax liabilities of $12 million, and a decrease to Other non-current assets of $26 million on the Condensed Consolidated Statement of Financial Position through a cumulative adjustment of $15 million decrease to Retained earnings. For the three and six months ended June 30, 2018, the impact of adopting this standard on the Condensed Consolidated Statement of Income was insignificant.
Statement of Cash Flows
In August 2016, the FASB issued new accounting guidance on the classification of certain cash receipts and cash payments. Under the new guidance, an entity no longer has discretion to choose the classification for a number of transactions, including contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, and distributions received from equity method investees. The new standard was effective for the Company in the first quarter of 2018. The adoption of this guidance had no impact on the Company’s Condensed Consolidated Statements of Cash Flows.
Financial Assets and Liabilities
In January 2016, the FASB issued new accounting guidance on recognition and measurement of financial assets and financial liabilities. The amendments in the new guidance make targeted improvements, which include the requirement to measure equity investments with readily determinable fair values at fair value through net income, simplification of the impairment assessment for equity investments without readily determinable fair values, adjustments to existing and additional disclosure requirements, and additional tax considerations. The Company applied the amendments by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption, with the exception of the amendments related to equity securities without readily determinable fair values, including disclosure requirements, which were applied prospectively. Upon the adoption of this guidance on January 1, 2018, the Company recognized an increase to Accumulated other comprehensive loss of $1 million on the Condensed Consolidated Statement of Financial Position through a cumulative adjustment of $1 million increase to Retained earnings. For the three and six months ended June 30, 2018, the impact of adopting this standard on the Condensed Consolidated Statement of Income was insignificant.
Revenue Recognition
In May 2014, the FASB issued a new accounting standard on revenue from contracts with customers (the “Standard” or “ASC 606”), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP (“ASC 605”). The core principal of the Standard is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Standard also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments, changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. Two methods of transition were permitted upon adoption: full retrospective and modified retrospective. The Company elected to apply the modified retrospective adoption approach to all contracts. Under this approach, prior periods were not restated. Rather, revenues and other disclosures for prior periods were provided in the notes to the financial statements as
8

previously reported under ASC 605, and the cumulative effect of initially applying the guidance was recognized as an adjustment to Retained earnings.
The following summarizes the significant changes to the Company as a result of the adoption of ASC 606 on January 1, 2018.

• | The Company previously recognized revenue either at a point in time or over a period of time based on the transfer of value to customers or as the remuneration became determinable. Under ASC 606, the revenue related to certain brokerage services recognized over a period of time is recognized on the effective date of the associated policies when control of the policy transfers to the customer. As a result, revenue from these arrangements are typically recognized in earlier periods under ASC 606 in comparison to ASC 605, changing the timing and amount of revenue recognized for annual and interim periods. This change resulted in a significant shift in timing of interim revenue for the Reinsurance Solutions revenue line and, to a lesser extent, certain other brokerage services.

• | The Standard provides guidance on accounting for certain revenue-related costs including when to capitalize costs associated with obtaining and fulfilling a contract. The majority of these costs were previously expensed as incurred under ASC 605. Assets recognized for the costs to obtain a contract, which includes certain sales commissions, are amortized on a systematic basis that is consistent with the transfer of the services to which the asset relates, considering anticipated renewals when applicable. For situations where the renewal period is one year or less and renewal costs are commensurate with the initial contract, the Company applied a practical expedient and recognizes the costs of obtaining a contract as an expense when incurred. Assets recognized as costs to fulfill a contract, which includes internal costs related to pre-placement broking activities, as well as other costs, are amortized on a systematic basis that is consistent with the transfer of the services to which the asset relates, which is generally less than one year.

As a result of applying the modified retrospective method to adopt ASC 606, the following adjustments were made to the Condensed Consolidated Statement of Financial Position as of January 1, 2018:

|  | December 31, 2017 |  |  |  | January 1, 2018

Accounting Standards Issued But Not Yet Adopted
Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income
In February 2018, the FASB issued new accounting guidance related to reclassification of certain tax effects from accumulated other comprehensive income. The guidance allows a reclassification from accumulated comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (“the Tax Reform Act”). In addition, the entity is required to provide certain disclosures regarding stranded tax effects. The guidance is effective for Aon in the first quarter of 2019 and early adoption is permitted, including adoption in any interim period. The guidance should be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. The Company is currently evaluating the impact that the guidance will have on the Financial Statements and the period in which it plans to adopt. Refer to Note 11 “Income Taxes” for further discussion of the Tax Reform Act.
Targeted Improvements to Accounting for Hedging Activities
In August 2017, the FASB issued new accounting guidance on targeted improvements to accounting for hedging activities. The new guidance amends its hedge accounting model to enable entities to better portray their risk management activities in the Financial Statements. The guidance eliminates the requirement to separately measure and report hedge ineffectiveness and requires the effect of a hedging instrument to be presented in the same income statement line as the hedged item. An entity will apply the new guidance on a modified retrospective basis with a cumulative effect adjustment to accumulated other comprehensive income with a corresponding adjustment to retained earnings as of the beginning of the period of adoption. Changes to income statement presentation and financial statement disclosures will be applied prospectively. The new guidance is effective for Aon in the first quarter of 2019 and early adoption is permitted. The Company is currently evaluating the impact that the standard will have on the Financial Statements and the period of adoption.
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 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. An entity will apply the new guidance on a prospective basis. The new guidance is effective for Aon in the first quarter of 2020 and early adoption is permitted. The Company is currently evaluating the impact that the standard will have on the Financial Statements and the period of adoption.
Credit Losses
In June 2016, the FASB issued new accounting guidance on the measurement of credit losses on financial instruments. The new guidance 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. An entity will apply the new guidance through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The guidance is effective for Aon in the first quarter of 2020 and early adoption is permitted beginning in the first quarter of 2019. Aon is currently evaluating the impact that the standard will have on its Financial Statements, as well as the period of adoption.
Leases
In February 2016, the FASB issued a new accounting standard on leases, which requires lessees to recognize assets and liabilities for most leases. Under the new standard, a lessee should recognize in the Condensed Consolidated Statement of Financial Position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee have not significantly changed from current U.S. GAAP standards. The new standard will be effective for the Company in the first quarter of 2019,
11

with early adoption permitted. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. These practical expedients relate to the identification and classification of leases that commenced before the effective date, initial direct costs for leases that commenced before the effective date, and the ability to use hindsight in evaluating lessee options to extend or terminate a lease or to purchase the underlying asset.
The Company is currently evaluating the impacts of the new accounting standard and is in the process of developing and implementing operational processes, including a system solution, to address the identified impacts. The Company expects to recognize significant lease liabilities and corresponding right of use assets on its Condensed Consolidated Statements of Financial Position, but is unable to provide quantitative information at this time. The Company has implemented a comprehensive approach to review existing arrangements that may contain a lease, and is performing completeness assessments over the identified lease population and assessing system requirements in order to determine the appropriate accounting upon transition and on an ongoing basis.
Additionally, the Company expects to expand its disclosures around lease arrangements. The Company expects to adopt the new accounting standard in the first quarter of 2019 and is currently evaluating the practical expedients that will be applied.
3. Revenue from Contracts with Customers
The Company generates revenues primarily through commissions, compensation from insurance and reinsurance companies for services provided to them, and fees from clients. Commissions and fees for brokerage services vary depending upon several factors, which may include the amount of premium, the type of insurance or reinsurance coverage provided, the particular services provided to a client, insurer, or reinsurer, and the capacity in which the Company acts. Compensation from insurance and reinsurance companies includes fees for consulting and analytics services and fees and commissions for administrative and other services provided to or on behalf of insurers. Fees from clients for advice and consulting services are dependent on the extent and value of the services provided. Payment terms are consistent with current industry practices.
The Company recognizes revenue when control of the promised services is transferred to the customer in the amount that best reflects the consideration to which the Company expects to be entitled in exchange for those services. For arrangements where control is transferred over time, an input or output method is applied that represents a faithful depiction of the progress towards completion of the performance obligation. For arrangements that include variable consideration, the Company assesses whether any amounts should be constrained. For arrangements that include multiple performance obligations, the Company allocates consideration based on their relative fair values.
Costs incurred by the Company in obtaining a contract are capitalized and amortized on a systematic basis that is consistent with the transfer of control of the services to which the asset relates, considering anticipated renewals when applicable. Certain contract related costs, including pre-placement brokerage costs, are capitalized as a cost to fulfill and are amortized on a systematic basis consistent with the transfer of control of the services to which the asset relates, which is generally less than one year.
The Company has elected to apply practical expedients to not disclose the revenue related to unsatisfied performance obligations if (1) the contract has an original duration of 1 year or less, (2) the Company has recognized revenue for the amount in which it has the right to bill, and (3) the variable consideration is allocated entirely to an unsatisfied performance obligation which is recognized as a series of distinct goods or services that form a single performance obligation.
Disaggregation of Revenue
The following is a description of principal service lines from which the Company generates its revenue:
Commercial Risk Solutions includes retail brokerage, cyber solutions, global risk consulting, and captives. Revenue primarily includes insurance commissions and fees for services rendered. Revenues will generally be recognized at a point in time upon the effective date of the underlying policy or over the term of the arrangement to depict the transfer of control of the services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those services. Revenues are recorded net of allowances for estimated policy cancellations, which are determined based on an evaluation of historical and current cancellation data.
12

Reinsurance Solutions includes treaty and facultative reinsurance brokerage and capital markets. Revenue primarily includes reinsurance commissions and fees for services rendered. Revenues will generally be recognized at a point in time upon the effective date of the underlying policy (or policies) or over the term of the arrangement to depict the transfer of control of the services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those services.
Retirement Solutions includes core retirement, investment consulting, and talent, rewards & performance. Revenue consists primarily of fees paid by clients for consulting services, such as risk management strategies, health and benefits, and human capital consulting services. Revenue recognized for these arrangements are typically recognized at a point-in-time upon completion of the service or over time to depict the transfer of control of the services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those services. For consulting arrangements recognized over-time, revenue will be recognized based on a measure of progress that depicts the transfer of control of the services to the customer, utilizing an appropriate input or output measure. Fees paid by clients for consulting services are typically charged on an hourly, project or fixed-fee basis. Revenues from time-and-materials or cost-plus arrangements are recognized as services are performed. Reimbursements received for out-of-pocket expenses are recorded as a component of revenue.
Health Solutions includes health and benefits brokerage and healthcare exchanges. Revenue primarily includes insurance commissions and fees for services rendered. For brokerage commissions, revenue is typically recognized at the effective date of the underlying policy (or policies) or over the term of the arrangement to depict the transfer of control of the services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those services. Revenues from health care exchange arrangements are typically recognized upon successful enrollment of participants, net of a reserve for estimated cancellations.
Data & Analytic Services includes Affinity, Aon InPoint, and ReView. Revenue consists primarily of fees for services rendered and is generally recognized over the term of the arrangement to depict the transfer of control of the services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those services. For Data & Analytic Services arrangements recognized over-time, revenue will be recognized based on a measure of progress that depicts the transfer of control of the services to the customer, utilizing an appropriate input or output measure.

Contract Costs
The Company recognizes an asset for costs incurred to fulfill a contract for costs that are specifically identified and relate to a contract or anticipated contract, generate or enhance resources used in satisfying the Company’s performance obligations, and are expected to be recovered. Assets recognized as costs to fulfill a contract, which includes internal costs related to pre-placement
13

broking activities, as well as other costs, are amortized on a systematic basis that is consistent with the transfer of control of the services to which the asset relates. The amortization is primarily included in Compensation and benefits on the Condensed Consolidated Statements of Income.
The changes in the net carrying amount of costs to fulfill contracts with customers are as follows (in millions):

|  | Three months ended June 30, 2018 |  | Six months ended June 30, 2018

(1) | Upon adoption of the new revenue recognition standard on January 1, 2018, Aon capitalized $298 million of costs to fulfill contracts with customers.

The Company capitalizes incremental costs to obtain a contract with a customer that are expected to be recovered. Assets recognized for the costs to obtain a contract, which includes certain sales commissions, will be amortized on a systematic basis that is consistent with the transfer of control of the services to which the asset relates, considering anticipated renewals when applicable. For situations where the renewal period is one year or less and renewal costs are commensurate with the initial contract, the Company has applied a practical expedient and recognized the costs of obtaining a contract as an expense when incurred. The amortization is primarily included in Compensation and benefits on the Condensed Consolidated Statements of Income.
The changes in the net carrying amount of costs to obtain contracts with customers are as follows (in millions):

|  | Three months ended June 30, 2018 |  | Six months ended June 30, 2018

4. Discontinued Operations
On February 9, 2017, the Company entered into a Purchase Agreement with Tempo Acquisition, LLC (the “Purchase Agreement”) to sell its benefits administration and business process outsourcing business (the “Divested Business”) to an entity formed and controlled by affiliates of The Blackstone Group L.P. (the “Buyer”) and certain designated purchasers that are direct or indirect subsidiaries of the Buyer.
On May 1, 2017, the Buyer purchased all of the outstanding equity interests of the Divested Business, plus certain related assets and liabilities, for a purchase price of $4.3 billion in cash paid at closing, subject to customary adjustments set forth in the Purchase Agreement, and deferred consideration of up to $500 million (the “Transaction”). Cash proceeds after customary adjustments and before taxes due were $4.2 billion.
Aon and the Buyer entered into certain transaction related agreements at the closing, including two commercial agreements, a transition services agreement, certain intellectual property license agreements, sub-leases, and other customary agreements. Aon expects to continue to be a significant client of the Divested Business and the Divested Business has agreed to use Aon for its broking and other services for a specified period of time.
14

The financial results of the Divested Business for the three and six months ended June 30, 2018 and 2017 are presented as Income from discontinued operations on the Company’s Condensed Consolidated Statements of Income. The following table presents the financial results of the Divested Business (in millions):

Net income from discontinued operations |  | $ | 1 |  |  | $ | 821 |  |  | $ | 7 |  |  | $ | 861 |

Upon triggering held for sale criteria in February 2017, Aon ceased depreciating and amortizing all long-lived assets included in discontinued operations. Total operating expenses for 2017 include $8 million of depreciation of fixed assets and $11 million of intangible asset amortization for the time prior to the Company triggering held for sale criteria.
The Company’s Condensed Consolidated Statements of Cash Flows present the operating, investing, and financing cash flows of the Divested Business as discontinued operations. Aon uses a centralized approach to cash management and financing of its operations. Prior to the closing of the Transaction, portions of the Divested Business’s cash were transferred to Aon daily, and Aon would fund the Divested Business as needed. There were no Cash and cash equivalents of discontinued operations at June 30, 2017. Total proceeds received for the sale of the divested business and taxes paid as a result of the sale are recognized on the Condensed Consolidated Statements of Cash Flows in Cash provided by investing activities - continuing operations and Cash provided by operating activities - continuing operations, respectively.
5. Cash and Cash Equivalents and Short-term Investments
Cash and cash equivalents include cash balances and all highly liquid instruments with initial maturities of three months or less. Short-term investments consist of money market funds. The estimated fair value of cash and cash equivalents and short-term investments approximates their carrying values.
At June 30, 2018, Cash and cash equivalents and Short-term investments were $660 million compared to $1,285 million at December 31, 2017, a decrease of $625 million. Of the total balances, $99 million and $96 million were restricted as to their use at June 30, 2018 and December 31, 2017, respectively. Included within the June 30, 2018 and December 31, 2017 balances was £42.7 million ($56.5 million at June 30, 2018 exchange rates and $57.1 million at December 31, 2017 exchange rates) of operating funds required to be held by the Company in the United Kingdom by the Financial Conduct Authority (the “FCA”), a U.K.-based regulator, which were included in Short-term investments.

The results of operations related to these assets and liabilities are included in continuing operations, as the criteria to be presented as a discontinued operation were not satisfied. The assets and liabilities are expected to be disposed in the second half of 2018.
19

A non-cash impairment charge of $176 million was recognized to write down the assets and liabilities to a fair value less cost to sell of $47 million and $41 million, respectively. The impairment charge was recognized in Amortization and impairment of intangible assets on the Condensed Consolidated Statement of Income for the three and six months ended June 30, 2018.
8. Restructuring
In 2017, Aon initiated a global restructuring plan (the “Restructuring Plan”) in connection with the sale of the Divested Business. The Restructuring Plan is intended to streamline operations across the organization and deliver greater efficiency, insight, and connectivity. The Company expects these restructuring activities and related expenses to affect continuing operations through 2019, including an estimated 4,200 to 4,800 role eliminations. The Restructuring Plan is expected to result in cumulative costs of approximately $1,025 million through the end of the plan, consisting of approximately $420 million in employee termination costs, $130 million in technology rationalization costs, $60 million in lease consolidation costs, $40 million in non-cash asset impairments, and $375 million in other costs, including certain separation costs associated with the sale of the Divested Business.
From the inception of the Restructuring Plan through June 30, 2018, the Company has eliminated 3,337 positions and incurred total expenses of $766 million for restructuring and related separation costs. These charges are included in Compensation and benefits, Information technology, Premises, Depreciation of fixed assets, and Other general expenses in the accompanying Condensed Consolidated Statements of Income.
The following table summarizes restructuring and separation costs by type that have been incurred through June 30, 2018 and are estimated to be incurred through the end of the Restructuring Plan (in millions). Estimated costs may be revised in future periods as these assumptions are updated:

|  | Three months ended June 30, 2018 |  | Six months ended June 30, 2018 |  | Inception to Date |  | Estimated Remaining Costs |  | Estimated Total Cost (1)

(1) | Actual costs, when incurred, may vary due to changes in the assumptions built into the Restructuring Plan. Significant assumptions that may change when plans are finalized and implemented include, but are not limited to, changes in severance calculations, changes in the assumptions underlying sublease loss calculations due to changing market conditions, and changes in the overall analysis that might cause the Company to add or cancel component initiatives.

(2) | Total contract termination costs incurred under the Restructuring Plan associated with Technology rationalizations, Lease consolidations, and Other costs associated with restructuring and separation, respectively, for the three months ended June 30, 2018 were $0 million, $10 million, and $75 million; for the six months ended June 30, 2018 were, respectively, $1 million, $12 million, and $79 million; and since inception of the Restructuring Plan were, respectively, $2 million, $20 million, and $82 million. Total estimated contract termination costs expected to be incurred under the Restructuring Plan associated with Technology rationalizations, Lease consolidations, and Other costs associated with restructuring and separation, respectively, are $15 million, $80 million, and $82 million.

(3) | Other costs associated with the Restructuring Plan include those to separate the Divested Business, as well as moving costs, and consulting and legal fees. These costs are generally recognized when incurred.

Revolving Credit Facilities
As of June 30, 2018, Aon plc had two primary committed credit facilities outstanding: its $900 million multi-currency U.S. credit facility expiring in February 2021 (the “2021 Facility”) and its $400 million multi-currency U.S. credit facility expiring in October 2022 (the “2022 Facility”).
21

Each of these facilities includes customary representations, warranties and covenants, including financial covenants that require Aon to maintain specified ratios of adjusted consolidated earnings before interest, taxes, depreciation, and amortization (“EBITDA”) to consolidated interest expense and consolidated debt to adjusted consolidated EBITDA, in each case, tested quarterly. At June 30, 2018, Aon did not have borrowings under the 2021 Facility or the 2022 Facility, and was in compliance with the financial covenants and all other covenants contained therein during the rolling twelve months ended June 30, 2018.
Commercial Paper
Aon Corporation, a wholly-owned subsidiary of Aon plc, has established a U.S. commercial paper program and Aon plc has established a European multi-currency commercial paper program (collectively, the “CP Programs”). Commercial paper may be issued in aggregate principal amounts of up to $600 million under the U.S. program and €525 million under the European program, not to exceed the amount of the Company’s committed credit, which was $1.3 billion at June 30, 2018. The U.S. commercial paper program is fully and unconditionally guaranteed by Aon plc and the European commercial paper program is fully and unconditionally guaranteed by Aon Corporation.
Commercial paper outstanding, which is included in Short-term debt and current portion of long-term debt in the Company’s Condensed Consolidated Statements of Financial Position, is as follows (in millions):

As of |  | June 30, 2018 |  | December 31, 2017

Weighted average interest rate of commercial paper outstanding |  | 0.92 | % |  | 0.26 | % |  | 0.85 | % |  | 0.18 | %

11. Income Taxes
The effective tax rates on net income from continuing operations were 165.5% and (4.8)% for the three and six months ended June 30, 2018, respectively. The effective tax rates on net income from continuing operations were 76.9% and (181.0)% for the three and six months ended June 30, 2017, respectively. For the three months ended June 30, 2018, the Company reported a tax benefit of $144 million on a pretax loss of $87 million, which resulted in an effective tax rate of 165.5%. For the six months ended June 30, 2018, the Company reported a tax benefit of $30 million on pretax income of $631 million, which resulted in an effective tax rate of (4.8)%. The primary drivers of the tax rates for the three and six months ended June 30, 2018 include the following:

• | The geographical distribution of income including restructuring charges and legacy litigation as well as the impairment of certain assets and liabilities classified as held for sale.

• | Certain discrete items including the net tax benefit associated with the anticipated sale of certain assets and liabilities classified as held for sale, the impact of share-based payments, changes in uncertain tax positions, and the deferred remeasurement related to the anticipated acceleration of contributions to the qualified U.S. pension plan. The deferred remeasurement also impacted the Company’s provisional estimates.

On December 22, 2017, the Tax Reform Act was enacted into law and the new legislation contains several key tax provisions that impact the Company, including a reduction of the corporate income tax rate to 21% effective for tax years beginning after December 31, 2017 and a one-time mandatory transition tax on accumulated foreign earnings (the “Transition Tax”), among others. Also on December 22, 2017, the Securities and Exchange Commission (the “SEC”) staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address the application of U.S. GAAP in situations when a registrant did not have the necessary information available, prepared, or analyzed in reasonable detail to complete the accounting for certain income tax effects of Tax Reform Act in the period of enactment. SAB 118 allowed registrants to record provisional amounts during a one year measurement period.
In the fourth quarter of 2017, a net provisional charge of $345 million was recorded which included the Transition Tax, the re-measurement of existing deferred tax balances, as well as local country income taxes, state income taxes and withholding taxes expected to be due upon repatriation of the earnings subject to the Transition Tax. In addition, the Company was unable to estimate the allocation between continuing and discontinued operations of the tax benefit from foreign tax credits generated in 2017 and related valuation allowance release.
22

In the second quarter of 2018, the Company took the following actions with respect to its provisional estimates:

• | Adjusted its provisional estimate of the remeasurement of deferred taxes to reflect the anticipated acceleration of contributions to the qualified U.S. pension plan in the third quarter of 2018. The change reduced the provisional charge by $11 million and impacted the effective tax rate by 12.6% and (1.7)% for the three and six months ended June 30, 2018, respectively.

• | Updated its state tax analysis to consider legislation enacted by the states in the second quarter, which did not result in a significant adjustment.

• | Continued to update the underlying calculations for the Transition Tax but did not record any significant adjustments. Additional guidance from the U.S. Treasury related to the calculation of the Transition Tax is expected in the third quarter of 2018.

The Company will finalize the amounts by the end of 2018 after completing its reviews, analyzing guidance issued during the measurement period, and evaluating the local tax rules where the Company has pools of undistributed earnings within our complex legal entity structure.
12. Shareholders’ Equity
Ordinary Shares
Aon has a share repurchase program authorized by the Company’s Board of Directors (the “Repurchase Program”). The Repurchase Program was established in April 2012 with up to $5.0 billion in authorized repurchases, and was increased by $5.0 billion in authorized repurchases in each of November 2014 and February 2017 for a total of $15.0 billion in repurchase authorizations.
Under the Repurchase Program, Class A Ordinary Shares may be repurchased through the open market or in privately negotiated transactions, from time to time, based on prevailing market conditions, and will be funded from available capital.
The following table summarizes the Company’s Share Repurchase activity (in millions, except per share data):

In March 2017, the Company approved a plan to offer a voluntary one-time lump sum payment option to certain eligible employees of the Company’s U.K. pension plans that, if accepted, would settle the Company’s pension obligations to them. The lump sum cash payment offer will close during 2018. As of June 30, 2018, lump sum payments from plan assets of £99 million ($132 million using June 30, 2018 exchange rates) were paid. As a result of this settlement, the Company remeasured the assets and liabilities of the U.K. pension plan during the second quarter of 2018, which in aggregate resulted in a reduction to the projected benefit obligation of £87 million ($115 million using June 30, 2018 exchange rates), as well as a non-cash settlement charge of £12 million ($16 million using average June 30, 2018 exchange rates) in the second quarter of 2018 and £17 million ($23 million using average exchange rates) for the six months ended June 30, 2018. Additional non-cash settlement charges are expected in 2018.
Contributions
The Company expects to make cash contributions of approximately $92 million, $143 million, and $22 million, based on exchange rates as of December 31, 2017, to its significant U.K., U.S., and other significant international pension plans, respectively, during 2018. This includes the Company’s anticipated acceleration of contributions to the qualified U.S. pension plan of approximately $100 million in the third quarter of 2018, which will allow the pension contribution tax deduction to be taken at the 2017 federal tax rate of 35%.
During the three months ended June 30, 2018, cash contributions of $25 million, $8 million, and $3 million were made to the Company’s significant U.K., U.S., and other significant international pension plans, respectively. During the six months ended June 30, 2018, cash contributions of $48 million, $25 million, and $11 million were made to the Company’s significant U.K., U.S., and other significant international pension plans, respectively.
During the three months ended June 30, 2017, cash contributions of $26 million, $13 million, and $9 million were made to the Company’s significant U.K., U.S., and other significant international pension plans, respectively. During the six months ended
25

June 30, 2017, cash contributions of $42 million, $26 million, and $11 million were made to the Company’s significant U.K., U.S., and other significant international pension plans, respectively.
14. Share-Based Compensation Plans
The following table summarizes share-based compensation expense recognized in the Condensed Consolidated Statements of Income in Compensation and benefits (in millions):

| Three months ended June 30 |  | Six months ended June 30
| 2018 |  | 2017 |  | 2018 |  | 2017
Restricted share units (“RSUs”) | $ | 46 |  |  | $ | 46 |  |  | $ | 104 |  |  | $ | 101 |
Performance share awards (“PSAs”) | 23 |  |  | 21 |  |  | 39 |  |  | 40 |
Employee share purchase plans | 1 |  |  | 2 |  |  | 4 |  |  | 6 |
Total share-based compensation expense | $ | 70 |  |  | $ | 69 |  |  | $ | 147 |  |  | $ | 147 |

Restricted Share Units
RSUs generally vest between three and five years. The fair value of RSUs is based upon the market value of Aon plc ordinary shares at the date of grant. With certain limited exceptions, any break in continuous employment will cause the forfeiture of all non-vested awards. Compensation expense associated with RSUs is recognized on a straight-line basis over the requisite service period. Dividend equivalents are paid on certain RSUs, based on the initial grant amount.
The following table summarizes the status of the Company’s RSUs, including shares related to the Divested Business (shares in thousands, except fair value):

| Six months ended June 30, 2018 |  | Six months ended June 30, 2017
| Shares |  | Fair Value at Date of Grant |  | Shares |  | Fair Value at Date of Grant
Non-vested at beginning of period | 4,849 |  |  | $ | 104 |  |  | 6,195 |  |  | $ | 89 |
Granted | 1,352 |  |  | $ | 140 |  |  | 1,497 |  |  | $ | 121 |
Vested | (1,664 | ) |  | $ | 98 |  |  | (2,172 | ) |  | $ | 82 |
Forfeited | (109 | ) |  | $ | 109 |  |  | (522 | ) |  | $ | 92 |
Non-vested at end of period | 4,428 |  |  | $ | 117 |  |  | 4,998 |  |  | $ | 101 |

Unamortized deferred compensation expense amounted to $418 million as of June 30, 2018, with a remaining weighted-average amortization period of approximately 2.1 years.
Performance Share Awards
The vesting of PSAs is contingent upon meeting a cumulative level of earnings per share related performance over a three-year period. The actual issue of shares may range from 0-200% of the target number of PSAs granted, based on the terms of the plan and level of achievement of the related performance target. The grant date fair value of PSAs is based upon the market price of Aon plc ordinary shares at the date of grant. The performance conditions are not considered in the determination of the grant date fair value for these awards. Compensation expense is recognized over the performance period based on management’s estimate of the number of units expected to vest. Management evaluates its estimate of the actual number of shares expected to be issued at the end of the programs on a quarterly basis. The cumulative effect of the change in estimate is recognized in the period of change as an adjustment to Compensation and benefits in the Condensed Consolidated Statements of Income, if necessary. Dividend equivalents are not paid on PSAs.
Information as of June 30, 2018 regarding the Company’s target PSAs granted and shares that would be issued at current performance levels for PSAs granted during the six months ended June 30, 2018 and the years ended December 31, 2017 and 2016, respectively, is as follows (shares in thousands and dollars in millions, except fair value):

| June 30, 2018 |  | December 31, 2017 |  | December 31, 2016
Target PSAs granted during period | 564 |  |  | 548 |  |  | 750 |
Weighted average fair value per share at date of grant | $ | 134 |  |  | $ | 114 |  |  | $ | 100 |
Number of shares that would be issued based on current performance levels | 564 |  |  | 941 |  |  | 742 |
Unamortized expense, based on current performance levels | $ | 68 |  |  | $ | 58 |  |  | $ | 12 |

15. Derivatives and Hedging
The Company is exposed to market risks, including changes in foreign currency exchange rates and interest rates. To manage the risk related to these exposures, the Company enters into various derivative instruments that reduce these risks by creating offsetting exposures. The Company does not enter into derivative transactions for trading or speculative purposes.
Foreign Exchange Risk Management
The Company is exposed to foreign exchange risk when it earns revenues, pays expenses, enters into monetary intercompany transfers or other transactions denominated in a currency that differs from its functional currency. The Company uses foreign exchange derivatives, typically forward contracts, options and cross currency swaps, to reduce its overall exposure to the effects of currency fluctuations on cash flows. These exposures are hedged, on average, for less than two years. These derivatives are accounted for as hedges, and changes in fair value are recorded each period in Other comprehensive income (loss) in the Condensed Consolidated Statements of Comprehensive Income.
The Company also uses foreign exchange derivatives, typically forward contracts and options, to economically hedge the currency exposure of the Company’s global liquidity profile, including monetary assets or liabilities that are denominated in a non-functional currency of an entity, typically on a rolling 30-day basis, but may be for up to one year in the future. These derivatives are not accounted for as hedges, and changes in fair value are recorded each period in Other income (expense) in the Condensed Consolidated Statements of Income.
The notional and fair values of derivative instruments are as follows (in millions):

| Notional Amount |  | Net Amount of Derivative Assets Presented in the Statements of Financial Position (1) |  | Net Amount of Derivative Liabilities Presented in the Statements of Financial Position (2)
| June 30, 2018 |  | December 31, 2017 |  | June 30, 2018 |  | December 31, 2017 |  | June 30, 2018 |  | December 31, 2017

Total | $ | 983 |  |  | $ | 955 |  |  | $ | 21 |  |  | $ | 32 |  |  | $ | 5 |  |  | $ | 6 |

(1) | Included within Other current assets ($4 million at June 30, 2018 and $9 million at December 31, 2017) or Other non-current assets ($17 million at June 30, 2018 and $23 million at December 31, 2017).

(2) | Included within Other current liabilities ($1 million at June 30, 2018 and $3 million at December 31, 2017) or Other non-current liabilities ($4 million at June 30, 2018 and $3 million at December 31, 2017).

(3) | These contracts typically are for 30 day durations and executed close to the last day of the most recent reporting month, thereby resulting in nominal fair values at the balance sheet date.

The amounts of derivative gains (loss) reclassified from Accumulated other comprehensive loss into the Condensed Consolidated Statements of Income (effective portion) are as follows (in millions):

|  | Three Months Ended |  | Six Months Ended
|  | June 30, 2018 |  | June 30, 2017 |  | June 30, 2018 |  | June 30, 2017

Total |  | $ | (2 | ) |  | $ | (4 | ) |  | $ | (6 | ) |  | $ | 6 |

The Company estimates that approximately $10 million of pretax losses currently included within Accumulated other comprehensive loss will be reclassified in to earnings in the next twelve months.
The amount of gain (loss) recognized in income on the ineffective portion of derivatives for the three and six months ended June 30, 2018 and 2017 was insignificant.
During the three and six months ended June 30, 2018, the Company recorded a loss of $20 million and a loss of $11 million, respectively, in Other income (expense) for foreign exchange derivatives not designated or qualifying as hedges. During the three and six months ended June 30, 2017, the Company recorded a loss of $1 million and a gain of $0.4 million, respectively, in Other income (expense) for foreign exchange derivatives not designated or qualifying as hedges.
Net Investments in Foreign Operations Risk Management
The Company uses non-derivative financial instruments to protect the value of its investments in a number of foreign subsidiaries. In 2016, the Company designated a portion of its Euro-denominated commercial paper issuances as a non-derivative hedge of the foreign currency exposure of a net investment in its European operations. The change in fair value of the designated portion of the Euro-denominated commercial paper due to changes in foreign currency exchange rates is recorded in Foreign currency translation adjustment, a component of Accumulated other comprehensive loss, to the extent it is effective as a hedge. The foreign currency translation adjustment of the hedged net investments that is also recorded in Accumulated other comprehensive loss. Ineffective portions of net investment hedges, if any, are reclassified from Accumulated other comprehensive loss into earnings during the period of change.
As of June 30, 2018, the Company has €220 million ($256 million at June 30, 2018 exchange rates) of outstanding Euro-denominated commercial paper designated as a hedge of the foreign currency exposure of its net investment in its European operations. As of June 30, 2018, the unrealized gain recognized in Accumulated other comprehensive loss related to the net investment non derivative hedging instrument was $15 million.
The Company did not reclassify any deferred gains or losses related to net investment hedges from Accumulated other comprehensive loss to earnings during the three and six months ended June 30, 2018 and 2017. In addition, the Company did not incur any ineffectiveness related to net investment hedges during the three and six months ended June 30, 2018 and 2017.

16. Fair Value Measurements and Financial Instruments
Accounting standards establish a three tier fair value hierarchy that prioritizes the inputs used in measuring fair values as follows:

• | Level 1 — observable inputs such as quoted prices for identical assets in active markets;

• | Level 2 — inputs other than quoted prices for identical assets in active markets, that are observable either directly or indirectly; and

• | Level 3 — unobservable inputs in which there is little or no market data which requires the use of valuation techniques and the development of assumptions.

The following methods and assumptions are used to estimate the fair values of the Company’s financial instruments:
Money market funds consist of institutional prime, treasury, and government money market funds. The Company reviews treasury and government money market funds to obtain reasonable assurance that the fund net asset value is $1 per share, and reviews the floating net asset value of institutional prime money market funds for reasonableness.
Equity investments consist of domestic and international equity securities and equity derivatives valued using the closing stock price on a national securities exchange. Over the counter equity derivatives are valued using observable inputs such as underlying prices of the underlying security and volatility. On a sample basis the Company reviews the listing of Level 1 equity securities in the portfolio and agrees the closing stock prices to a national securities exchange, and independently verifies the observable inputs for Level 2 equity derivatives and securities.
Fixed income investments consist of certain categories of bonds and derivatives. Corporate, government, and agency bonds are valued by pricing vendors who estimate fair value using recently executed transactions and proprietary models based on observable inputs, such as interest rate spreads, yield curves, and credit risk. Asset-backed securities are valued by pricing vendors who estimate fair value using discounted cash flow models utilizing observable inputs based on trade and quote activity of securities with similar features. Fixed income derivatives are valued by pricing vendors using observable inputs such as interest rates and yield curves. The Company obtains an understanding of the models, inputs, and assumptions used in developing prices provided by its vendors through discussions with the fund managers. The Company independently verifies the observable inputs, as well as assesses assumptions used for reasonableness based on relevant market conditions and internal Company guidelines. If an assumption is deemed unreasonable, based on the Company’s guidelines, it is then reviewed by management and the fair value estimate provided by the vendor is adjusted, if deemed appropriate. These adjustments do not occur frequently and historically are not material to the fair value estimates used in the Financial Statements.
Derivatives are carried at fair value, based upon industry standard valuation techniques that use, where possible, current market-based or independently sourced pricing inputs, such as interest rates, currency exchange rates, or implied volatilities.
Debt is carried at outstanding principal balance, less any unamortized issuance costs, discount or premium. Fair value is based on quoted market prices or estimates using discounted cash flow analyses based on current borrowing rates for similar types of borrowing arrangements.

17. Commitments and Contingencies
Legal
Aon and its subsidiaries are subject to numerous claims, tax assessments, lawsuits and proceedings that arise in the ordinary course of business, which frequently include errors and omissions (“E&O”) claims. The damages claimed in these matters are or may be substantial, including, in many instances, claims for punitive, treble or extraordinary damages. While Aon maintains meaningful E&O insurance and other insurance programs to provide protection against certain losses that arise in such matters, Aon has exhausted or materially depleted its coverage under some of the policies that protect the Company and, consequently, is self-insured or materially self-insured for some claims. Accruals for these exposures, and related insurance receivables, when applicable, are included in the Condensed Consolidated Statements of Financial Position and have been recognized in Other general expenses in the Condensed Consolidated Statements of Income to the extent that losses are deemed probable and are reasonably estimable. These amounts are adjusted from time to time as developments warrant. Matters that are not probable and reasonably estimable are not accrued for in the financial statements.
The Company has included in the current matters described below certain matters in which (1) loss is probable, (2) loss is reasonably possible, that is, more than remote but not probable, or (3) there exists the reasonable possibility of loss greater than the accrued amount. In addition, the Company may from time to time disclose matters for which the probability of loss could be remote but the claim amounts associated with such matters are potentially significant. The reasonably possible range of loss for the matters described below for which loss is estimable, in excess of amounts that are deemed probable and estimable and therefore already accrued, is estimated to be between $0 and $0.1 billion, exclusive of any insurance coverage. These estimates are based on currently available information. As available information changes, the matters for which Aon is able to estimate may change, and the estimates themselves may change. In addition, many estimates involve significant judgment and uncertainty. For example, at the time of making an estimate, Aon may only have limited information about the facts underlying the claim, and predictions and assumptions about future court rulings and outcomes may prove to be inaccurate. Although management at present believes that the ultimate outcome of all matters described below, individually or in the aggregate, will not have a material adverse effect on the consolidated financial position of Aon, legal proceedings are subject to inherent uncertainties and unfavorable rulings or other events. Unfavorable resolutions could include substantial monetary or punitive damages imposed on Aon or its subsidiaries. If unfavorable outcomes of these matters were to occur, future results of operations or cash flows for any particular quarterly or annual period could be materially adversely affected.
Current Matters
A retail insurance brokerage subsidiary of Aon was sued on September 14, 2010 in the Chancery Court for Davidson County, Tennessee Twentieth Judicial District, at Nashville by a client, Opry Mills Mall Limited Partnership (“Opry Mills”) that sustained flood damage to its property in May 2010. The lawsuit seeks $200 million in coverage from numerous insurers with whom this Aon subsidiary placed the client’s property insurance coverage. The insurers contend that only $50 million in coverage (which has already been paid) is available for the loss because the flood event occurred on property in a high hazard flood zone. Opry Mills is seeking full coverage from the insurers for the loss and has sued this Aon subsidiary in the alternative for the same $150 million difference on various theories of professional liability if the court determines there is not full coverage. In addition, Opry Mills seeks prejudgment interest, attorneys’ fees and enhanced damages which could substantially increase Aon’s exposure. In March 2015, the trial court granted partial summary judgment in favor of plaintiffs and against the insurers, holding generally that the plaintiffs are entitled to $200 million in coverage under the language of the policies. In August 2015, a jury returned a verdict in favor of Opry Mills and against the insurers in the amount of $204 million. On January 26, 2018, the Tennessee Court of Appeals reversed and remanded, reversing summary judgment in favor of plaintiffs and concluding that coverage is limited to $50 million. Aon believes it has meritorious defenses and intends to vigorously defend itself against these claims.
A pensions consulting and administration subsidiary of Aon provided advisory services to the Trustees of the Gleeds pension fund in the United Kingdom and, on occasion, to the relevant employer of the fund. In April 2014, the High Court, Chancery Division, London found that certain governing documents of the fund that sought to alter the fund’s benefit structure and that had been drafted by Aon were procedurally defective and therefore invalid. No lawsuit naming Aon as a party was filed, although a tolling agreement was entered. The High Court decision says that the additional liabilities in the pension fund resulting from the alleged defect in governing documents amount to approximately £45 million ($60 million at June 30, 2018 exchange rates). In December 2014, the Court of Appeal granted the employer leave to appeal the High Court decision. At a hearing in October 2016, the Court of Appeal approved a settlement of the pending litigation. On October 31, 2016, the fund’s trustees and employer sued Aon in the High Court, Chancery Division, London, alleging negligence and breach of duty in relation to the governing documents. The proceedings were served on Aon on December 20, 2016. The claimants seek damages of approximately £70 million ($93 million at June 30, 2018 exchange rates). In February 2018, the claimants instructed new lawyers and notified Aon that the claimants intend to add their previous lawyers as defendants to the Aon lawsuit. Claimants will allege that the previous lawyers were responsible for some of the losses sought from Aon because the lawyers gave negligent legal advice during the course of the High
31

Court and Court of Appeal proceedings. The addition of the new parties will delay any potential trial until 2019. Aon believes that it has meritorious defenses and intends to vigorously defend itself against this claim.
On June 29, 2015, Lyttelton Port Company Limited (“LPC”) sued Aon New Zealand in the Christchurch Registry of the High Court of New Zealand. LPC alleges, among other things, that Aon was negligent and in breach of contract in arranging LPC’s property insurance program for the period covering June 30, 2010, to June 30, 2011. LPC contends that acts and omissions by Aon caused LPC to recover less than it otherwise would have from insurers for losses suffered in the 2010 and 2011 Canterbury earthquakes. LPC claims damages of approximately NZD 184 million ($126 million at June 30, 2018 exchange rates) plus interest and costs. Aon believes that it has meritorious defenses and intends to vigorously defend itself against these claims.
On October 3, 2017, Christchurch City Council (“CCC”) invoked arbitration to pursue a claim that it asserts against Aon New Zealand. Aon provided insurance broking services to CCC in relation to CCC’s 2010-2011 material damage and business interruption program. In December 2015, CCC settled its property and business interruption claim for its losses arising from the 2010-2011 Canterbury earthquakes against the underwriter of its material damage and business interruption program and the reinsurers of that underwriter. CCC contends that acts and omissions by Aon caused CCC to recover less in that settlement than it otherwise would have. CCC claims damages of approximately NZD 528 million ($362 million at June 30, 2018 exchange rates) plus interest and costs. Aon believes that it has meritorious defenses and intends to vigorously defend itself against these claims.
In April 2017, the FCA announced an investigation relating to suspected competition law breaches in the aviation and aerospace broking industry, which, for Aon in 2016, represented less than $100 million in global revenue. The European Commission has now assumed jurisdiction over the investigation in place of the FCA. Other antitrust agencies outside the European Union are also conducting formal or informal investigations regarding these matters. Aon intends to work diligently with all antitrust agencies concerned to ensure they can carry out their work as efficiently as possible. At this time, in light of the uncertainties and many variables involved, Aon cannot estimate the ultimate impact on our company from these investigations or any related private litigation, nor any damages, penalties, or fines related to them. There can be no assurance that the ultimate resolution of these matters will not have a material adverse effect on the Company’s consolidated financial position, results of operations, or liquidity.
Guarantees and Indemnifications
The Company provides a variety of guarantees and indemnifications to its customers and others. The maximum potential amount of future payments represents the notional amounts that could become payable under the guarantees and indemnifications if there were a total default by the guaranteed parties, without consideration of possible recoveries under recourse provisions or other methods. These amounts may bear no relationship to the expected future payments, if any, for these guarantees and indemnifications. Any anticipated amounts payable are included in the Company’s Financial Statements, and are recorded at fair value.
The Company expects that, as prudent business interests dictate, additional guarantees and indemnifications may be issued from time to time.
Redomestication
In connection with the redomicile of Aon’s headquarters (the “Redomestication”), the Company on April 2, 2012 entered into various agreements pursuant to which it agreed to guarantee the obligations of its subsidiaries arising under issued and outstanding debt securities. Those agreements included the (1) Amended and Restated Indenture, dated as of April 2, 2012, among Aon Corporation, Aon plc, and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”) (amending and restating the Indenture, dated as of September 10, 2010, between Aon Corporation and the Trustee), (2) Amended and Restated Indenture, dated as of April 2, 2012, among Aon Corporation, Aon plc and the Trustee (amending and restating the Indenture, dated as of December 16, 2002, between Aon Corporation and the Trustee), (3) Amended and Restated Indenture, dated as of April 2, 2012, among Aon Corporation, Aon plc and the Trustee (amending and restating the Indenture, dated as of January 13, 1997, as supplemented by the First Supplemental Indenture, dated as of January 13, 1997), and (4) First Supplemental Indenture, dated as of April 2, 2012, among Aon Finance N.S. 1, ULC, as issuer, Aon Corporation, as guarantor, Aon plc, as guarantor, and Computershare Trust Company of Canada, as trustee.
Sale of the Divested Business
In connection with the sale of the Divested Business, the Company guaranteed future operating lease commitments related to certain facilities assumed by the Buyer. The Company is obligated to perform under the guarantees if the Divested Business defaults on such leases at any time during the remainder of the lease agreements, which expire on various dates through 2024. As of June 30, 2018, the undiscounted maximum potential future payments under the lease guarantee is $93 million, with an estimated fair value of $20 million. No cash payments were made in connection to the lease commitments during the three and six months ended June 30, 2018.
32

Additionally, the Company is subject to performance guarantee requirements under certain client arrangements that were assumed by the Buyer. Should the Divested Business fail to perform as required by the terms of the arrangements, the Company would be required to fulfill the remaining contract terms, which expire on various dates through 2023. As of June 30, 2018, the undiscounted maximum potential future payments under the performance guarantees were $200 million, with an estimated fair value of $1 million. No cash payments were made in connection to the performance guarantees during the three and six months ended June 30, 2018.
Letters of Credit
Aon has entered into a number of arrangements whereby the Company’s performance on certain obligations is guaranteed by a third party through the issuance of letters of credit (“LOCs”). The Company had total LOCs outstanding of approximately $93 million at June 30, 2018, compared to $96 million at December 31, 2017. These LOCs cover the beneficiaries related to certain of Aon’s U.S. and Canadian non-qualified pension plan schemes and secure deductible retentions for Aon’s own workers compensation program. The Company has also obtained LOCs to cover contingent payments for taxes and other business obligations to third parties, and other guarantees for miscellaneous purposes at its international subsidiaries.
Premium Payments
The Company has certain contractual contingent guarantees for premium payments owed by clients to certain insurance companies. The maximum exposure with respect to such contractual contingent guarantees was approximately $89 million at June 30, 2018 compared to $95 million at December 31, 2017.
18. Segment Information
The Company operates as one segment that includes all of Aon’s continuing operations, which as a global professional services firm provides advice and solutions to clients focused on risk, retirement, and health through five revenue lines which make up its principal products and services. The Chief Operating Decision Maker (the “CODM”) assesses the performance of the Company and allocates resources based on one segment: Aon United.
The Company’s reportable operating segment has been determined using a management approach, which is consistent with the basis and manner in which Aon’s CODM uses financial information for the purposes of allocating resources and evaluating performance. The CODM assesses performance and allocates resources based on total Aon results against its key four metrics, including organic revenue growth, expense discipline, and collaborative behaviors that maximize value for Aon and its shareholders, regardless of which revenue line it benefits.
As Aon operates as one segment, segment profit or loss is consistent with consolidated reporting as disclosed on the Condensed Consolidated Statements of Income.
19. Guarantee of Registered Securities
As described in Note 17 “Commitments and Contingencies,” in connection with the Redomestication, Aon plc entered into various agreements pursuant to which it agreed to guarantee the obligations of Aon Corporation arising under issued and outstanding debt securities, including the 5.00% Notes due September 2020, the 8.205% Notes due January 2027, and the 6.25% Notes due September 2040 (collectively, the “Aon Corporation Notes”). Aon Corporation is a 100% indirectly owned subsidiary of Aon plc. All guarantees of Aon plc are full and unconditional. There are no other subsidiaries of Aon plc that are guarantors of the Aon Corporation Notes.
In addition, Aon Corporation entered into an agreement pursuant to which it agreed to guarantee the obligations of Aon plc arising under the 4.25% Notes due December 2042 exchanged for Aon Corporation’s outstanding 8.205% Notes due January 2027, and also agreed to guarantee the obligations of Aon plc arising under the 4.45% Notes due May 2043, the 4.00% Notes due November 2023, the 2.875% Notes due May 2026, the 3.50% Notes due June 2024, the 4.60% Notes due June 2044, the 4.75% Notes due May 2045, the 2.80% Notes due March 2021, and the 3.875% Notes due December 2025 (collectively, the “Aon plc Notes”). All guarantees of Aon Corporation are full and unconditional. There are no subsidiaries of Aon plc, other than Aon Corporation, that are guarantors of the Aon plc Notes. As a result of the existence of these guarantees, the Company has elected to present the financial information set forth in this footnote in accordance with Rule 3-10 of Regulation S-X.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
EXECUTIVE SUMMARY OF SECOND QUARTER 2018 FINANCIAL RESULTS
Aon plc (“Aon”, the “Company”, “We”, or “Our”). is a leading global professional services firm providing a broad range of risk, retirement, and health solutions underpinned by proprietary data and analytics. Management is leading a 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.
Financial Results
In the first quarter of 2018, Aon adopted new accounting guidance related to the treatment of revenue from contracts with customers that was applied prospectively on the U.S. GAAP financial statements and therefore comparable periods have not been restated. Refer to Note 2 “Accounting Principles and Practices” for further information surrounding the quantitative and qualitative impacts of adopting ASC 606.
The following is a summary of our second quarter of 2018 financial results from continuing operations on a reported basis:

• | For the second quarter of 2018, revenue increased 8%, or $193 million, to $2.6 billion compared to the prior year period due primarily to organic revenue growth of 5%, a 3% increase related to acquisitions, net of divestitures, and a 2% favorable impact from foreign currency exchange rates. For the six months ended June 30, 2018, revenue increased 19%, or $902 million, to $5,651 million compared to the prior year period due primarily to a 8% increase related to the adoption of the new revenue recognition standard in 2018, organic revenue growth of 4%, a 4% favorable impact from foreign currency exchange rates, and a 3% increase related to acquisitions, net of divestitures.

• | Operating expenses for the second quarter of 2018 were $2.6 billion, an increase of $82 million compared to the prior year period. The increase was due primarily to a $176 million non-cash impairment charge related to certain assets and liabilities classified as held for sale, a $103 million increase in expense related to legacy litigation, a $72 million increase in operating expenses related to acquisitions, net of divestitures, a $44 million unfavorable impact from foreign currency translation, a $40 million increase in restructuring charges, an $11 million increase related to the adoption of the new revenue recognition standard in 2018, and an increase in expense associated with 5% organic revenue growth, partially offset by a $380 million decrease in non-cash impairment charges to the tradenames associated with the sale of the Divested Business, $40 million of incremental savings related to restructuring and other operational improvement initiatives, and a $34 million decrease of costs related to regulatory and compliance matters. Operating expenses for the first six months of 2018 increased $327 million compared to the prior year period primarily due to a $176 million non-cash impairment charge related to certain assets and liabilities classified as held for sale, a $143 million unfavorable impact from foreign currency translation, a $138 million increase in expense associated with acquisitions, net of divestitures, a $103 million increase in expense related to legacy litigation, a $76 million increase related to the adoption of the new revenue recognition standard in 2018, $73 million of accelerated amortization related to tradenames, and an increase in expense associated with 4% organic revenue growth, partially offset by $380 million decrease in non-cash impairment charges to the tradenames associated with the sale of the Divested Business, $92 million of incremental savings related to restructuring and other operational improvement initiatives, a $34 million decrease of costs related to regulatory and compliance matters, and a $30 million decrease in restructuring charges.

• | Operating margin increased to (0.6)% in the second quarter of 2018 from (5.4)% in the prior year period, including a decrease of 30 basis points resulting from adoption of the new revenue recognition standard in 2018. The underlying increase was driven by organic revenue growth of 5% and strong core operational improvement, partially offset by an increase in expense due to the factors listed above. Operating margin for the first six months of 2018 increase d to 13.9% from 4.4% in the prior year period, including an increase of 530 basis points resulting from the adoption of the new revenue recognition standard in 2018. The increase from the prior year period was driven by organic revenue growth of 4% and strong core operational improvement, partially offset by an increase in expense due to the factors listed above.

• | Due to the factors set forth above, net income from continuing operations increased $100 million, or 233%, to $57 million for the second quarter of 2018 compared to the prior year period. During the first six months of 2018, net income from continuing operations increased $439 million, or 198%, to $661 million compared to the first six months of 2017.

• | Diluted earnings per share from continuing operations was $0.19 per share for the second quarter of 2018 compared to $(0.20) per share for the prior year period, including a decrease of $0.02 per share resulting from the adoption of the new revenue recognition standard. During the first six months of 2018, diluted earnings per share from continuing operations was $2.55 per share compared to $0.75 per share for the prior year period, including an increase of $1.05 per share resulting from the adoption of the new revenue recognition standard.

44

• | Cash flow provided by operating activities was $413 million for the first six months of 2018, a decrease of $23 million from the prior year period. The decrease was driven primarily by a $67 million increase in cash restructuring payments, partially offset by operational improvement.

We focus on four key non-GAAP metrics that we communicate to shareholders: organic revenue growth, adjusted operating margin, adjusted diluted earnings per share, and free cash flow. These non-GAAP metrics should be viewed in addition to, not instead of, our Financial Statements. The following is our measure of performance against these four metrics from continuing operations for the second quarter of 2018:

• | Organic revenue growth, a non-GAAP measure defined under the caption “Review of Consolidated Results — Organic Revenue Growth,” was 5% for the second quarter of 2018, compared to 3% in the prior year period. Organic revenue growth was 4% for the first six months of 2018, consistent with 4% in the prior year period.

• | Adjusted operating margin, a non-GAAP measure defined under the caption “Review of Consolidated Results — Adjusted Operating Margin,” was 22.0% for the second quarter of 2018 compared to 22.0% in the prior year period. For the first six months of 2018, adjusted operating margin was 27.4% compared to 22.0% for the prior year period. The increase primarily reflects incremental restructuring savings and strong core performance.

• | Adjusted diluted earnings per share from continuing operations, a non-GAAP measure defined under the caption “Review of Consolidated Results — Adjusted Diluted Earnings per Share,” was $1.71 per share for the second quarter of 2018 and $4.69 in the first six months of 2018, compared to $1.45 per share and $2.90 per share for the respective prior year periods.

• | Free cash flow, a non-GAAP measure defined under the caption “Review of Consolidated Results — Free Cash Flow,” decreased in the first six months of 2018 by $52 million, or 15%, from the prior year period, to $302 million, driven by an increase of $29 million in capital expenditures, including investments in our operating model and a decrease of $23 million in cash flow from operations.

Revenue
Total revenue increased by 8%, or $193 million, in the second quarter of 2018 compared to the second quarter of 2017. This change reflects 5% organic revenue growth, a 3% increase related to acquisitions, net of divestitures, and a 2% favorable impact from foreign currency exchange rates. For the first six months of 2018, revenue increased by 19%, or $902 million, compared to the prior year period. This change reflects 8% related to the adoption of the new revenue recognition standard in 2018, 4% organic revenue growth, a 4% favorable impact from foreign currency exchange rates, and a 3% increase related to acquisitions, net of divestitures.
Commercial Risk Solutions organic revenue growth was 6% in the second quarter of 2018 and 5% in the first six months of 2018 compared to the prior year periods, driven by strong growth globally across most geographies, highlighted by particular strength in North America driven by new business generation and strong management of the renewal book portfolio.
46

Reinsurance Solutions organic revenue growth was 8% in the second quarter of 2018 and 6% in the first six months of 2018 compared to the prior year periods, driven by net new business generation in treaty and strong growth in facultative placements, partially offset by a modest decline in capital markets transactions given the prior year period benefited from record catastrophe bond issuance during the mid-year renewal season.
Retirement Solutions organic revenue growth was 3% in the second quarter of 2018 reflecting solid growth in core actuarial retirement driven by an increase in volume and rates across North America and the EMEA region, as well as solid growth in our talent practice for assessment services and in our rewards practice for data-driven services. In investment consulting, double-digit growth in our core delegated investment management business was more than offset by an unfavorable impact from the timing of certain performance-based fees earned in the prior year quarter. Organic revenue growth was 1% in the first six months of 2018 compared to the prior year periods, driven by growth in core actuarial retirement and in the talent practice for assessment services, partially offset by the impact from the timing of certain performance-based fees in investment consulting.
Health Solutions organic revenue growth was 7% in the second quarter of 2018 driven by growth across every major geography, highlighted by particular strength in the U.S. and double-digit growth in both Latin America and Asia. Strength in the U.S. was highlighted by another quarter of strong growth in voluntary benefits, an area where we have seen increasing client demand. Organic revenue growth was 2% in the first six months of 2018 compared to the prior year periods, driven by solid growth globally in health and benefits brokerage, partially offset by a decline in project-related work that benefited the prior year period in the health care exchange business.
Data & Analytic Services organic revenue growth was (4)% in the second quarter of 2018 and (1)% in the first six months of 2018 compared to the prior year periods, driven by the anticipated near-term unfavorable impact from changes in certain client contracts, most notably the transition of a certain government contract in our flood business, partially offset by solid growth internationally in our core Affinity business.
Compensation and Benefits
Compensation and benefits increased $28 million, or 2%, in the second quarter of 2018 compared to the second quarter of 2017. This increase was primarily driven by a $55 million increase in expenses related to acquisitions, net of divestitures, a $32 million unfavorable impact from foreign currency translation, a $13 million increase related to adoption of the new revenue recognition standard in 2018, and an increase in expense associated with 5% organic revenue growth, partially offset by a $69 million decrease in restructuring costs and $44 million of incremental savings related to restructuring and other operational improvement initiatives. For the first six months of 2018, compensation and benefits increased $175 million, or 6%, compared to the first six months of 2017. The increase was primarily driven by a $110 million unfavorable impact from foreign currency translation, a $106 million increase in expenses related to acquisitions, net of divestitures, a $78 million increase related to adoption of the new revenue recognition standard in 2018, and an increase in expense associated with 4% organic revenue growth, partially offset by a $139 million decrease in restructuring costs and $94 million of incremental savings related to restructuring and other operational improvement initiatives.
Information Technology
Information technology, which represents costs associated with supporting and maintaining our infrastructure, increased $25 million, or 26%, in the second quarter of 2018 compared to the second quarter of 2017. This increase was primarily driven by a $13 million increase in investments supporting growth initiatives and GDPR compliance, a $5 million increase in expenses related to acquisitions, net of divestitures, and a $2 million unfavorable impact from foreign currency translation. For the first six months of 2018, Information technology increased $52 million, or 28%, compared to the first six months of 2017. This increase was primarily driven by a $10 million increase in expenses related to acquisitions, net of divestitures, an $8 million increase in restructuring costs, a $5 million unfavorable impact from foreign currency translation, and an increase in investments supporting growth initiatives and GDPR compliance.
Premises
Premises, which represents the cost of occupying offices in various locations throughout the world, increased $10 million, or 12%, in the second quarter of 2018 compared to the second quarter of 2017. This increase was primarily driven by a $9 million increase in restructuring costs and a $3 million increase related to acquisitions, net of divestitures, partially offset by $1 million of incremental savings related to restructuring and other operational improvement initiatives. For the first six months of 2018, Premises increased $19 million, or 11%, compared to the first six months of 2017. This increase was primarily driven by a $9 million increase in restructuring costs, a $7 million unfavorable impact from foreign currency translation, and a $6 million increase related to acquisitions, net of divestitures, partially offset by $3 million of incremental savings related to restructuring and other operational improvement initiatives.
47

Depreciation of Fixed Assets
Depreciation of fixed assets primarily relates to software, leasehold improvements, furniture, fixtures and equipment, computer equipment, buildings, and automobiles. Depreciation of fixed assets decreased $7 million, or 13%, in the second quarter of 2018 compared to the second quarter of 2017. This decrease was primarily driven by a decrease in overall expense as we continue to optimize our portfolio. For the first six months of 2018, Depreciation of fixed assets decreased $22 million, or 20%, compared to the first six months of 2017. This decrease was primarily driven by a $15 million decrease in restructuring costs related to fixed asset write-offs and a decrease in overall expense as we continue to optimize our IT and real estate portfolios.
Amortization and Impairment of Intangibles Assets
Amortization and impairment of intangibles primarily relates to finite-lived tradenames and customer-related, contract-based, and technology assets. Amortization and impairment of intangibles decreased $178 million, or 39%, in the second quarter of 2018 compared to the second quarter of 2017 due to a $204 million net decrease in impairment charges, partially offset by a $19 million increase in accelerated amortization related to tradenames. For the first six months of 2018, Amortization and impairment of intangible assets decreased $111 million, or 22%, compared to the first six months of 2017. This decrease was primarily due to a $204 million net decrease in impairment charges, partially offset by a $73 million increase in accelerated amortization related to tradenames.
Other General Expenses
Other general expenses in the second quarter of 2018 increased $204 million, or 62%, compared to the second quarter of 2017 due primarily to a $103 million increase in legacy litigation, a $102 million increase in restructuring costs, and an increase in expense associated with 5% organic revenue growth, partially offset by a $34 million decrease of costs related to regulatory and compliance matters. For the first six months of 2018, Other general expenses increased $214 million, or 33%, compared to the prior year period. This increase was primarily driven by a $107 million increase in restructuring costs, $103 million increase in legacy litigation, a $15 million unfavorable impact from foreign currency translation, an $11 million increase related to acquisitions, net of divestitures, and an increase in expense associated with 4% organic revenue growth, partially offset by a $34 million decrease of costs related to regulatory and compliance matters.
Interest Income
Interest income represents income earned on operating cash balances and other income-producing investments. It does not include interest earned on funds held on behalf of clients. During the second quarter of 2018, Interest income was $1 million, compared to $8 million during the prior year period. For the first six months of 2018, Interest income was $5 million, a decrease from $10 million for the prior year period. The decrease in both periods reflects additional income earned on the proceeds of the Divested Business in the prior year period.
Interest Expense
Interest expense, which represents the cost of our debt obligations, was $69 million during the second quarter of 2018, a decrease from $71 million for the prior year period. For the first six months of 2018, Interest expense was $139 million, a decrease of $2 million from the prior year period. This decrease was due to a modest decrease in term debt outstanding.
Other Income (Expense)
Other expense was $3 million for the second quarter of 2018, compared to other income of $4 million for the second quarter of 2017. Other expense for the second quarter of 2018 primarily includes $27 million of losses on financial instruments and $7 million of pension and other postretirement expense, partially offset by $29 million of gains due to the favorable impact of exchange rates on the remeasurement of assets and liabilities in non-functional currencies. Other income of $4 million in the second quarter of 2017 primarily includes pension and other post-retirement income, partially offset by losses on financial instruments. Other expense was $18 million for the first six months of 2018, compared to other income of $2 million for the prior year period. Other expense for the first six months of 2018 primarily includes $27 million of losses on financial instruments, partially offset by $13 million of gains due to the favorable impact of exchange rates on the remeasurement of assets and liabilities in non-functional currencies. Other income for the first six months of 2017 primarily includes pension and other post-retirement income, partially offset by net losses due to the unfavorable impact of exchange rates on the remeasurement of monetary assets and liabilities in non-functional currencies and losses on certain foreign exchange hedging programs.

Income From Continuing Operations before Income Taxes
Due to the factors discussed above, losses from continuing operations before income taxes for the second quarter of 2018 was $87 million, a 53% increase from losses of $186 million in the second quarter of 2017, and income from continuing operations before income taxes was $631 million for the first six months of 2018, a 699% increase from $79 million from the first six months of 2017.
Income Taxes From Continuing Operations
The effective tax rates on net income from continuing operations were 165.5% and 76.9% for the second quarters of 2018 and 2017, respectively. The effective tax rates on net income from continuing operations were (4.8)% and (181.0)% for the six months ended June 30, 2018 and 2017, respectively. For the six months ended June 30, 2018, the Company reported a tax benefit of $30 million on pretax income of $631 million, which resulted in an effective tax rate of (4.8)%. The primary drivers of the year-to-date tax rate include the following:

• | The geographical distribution of income including restructuring charges and legacy litigation as well as the impairment of certain assets and liabilities classified as held for sale.

• | Certain discrete items including the net tax benefit associated with the anticipated sale of certain assets and liabilities classified as held for sale, the impact of share-based payments, changes in uncertain tax positions, and the deferred remeasurement related to the anticipated acceleration of contributions to the qualified U.S. pension plan.

Net Income from Discontinued Operations
Net income from discontinued operations decreased $820 million in the second quarter of 2018 and $854 million in the first six months of 2018 as compared to the prior year periods due to the execution of the sale of the Divested Business on May 2, 2017.
Net Income Attributable to Aon Shareholders
Net income attributable to Aon shareholders for the second quarter of 2018 decreased to $48 million, or $0.19 per diluted share, from $769 million, or $2.93 per diluted share, in the prior year period. Net income attributable to Aon shareholders for the first six months of 2018 decreased to $642 million, or $2.58 per diluted share, from $1,060 million, or $3.99 per diluted share, in the prior year period.
Non-GAAP Metrics
In our discussion of consolidated results, we sometimes refer to certain non-GAAP supplemental information derived from consolidated financial information specifically related to organic revenue growth, adjusted operating margin, adjusted diluted earnings per share, free cash flow, and the impact of foreign exchange rate fluctuations on operating results. This non-GAAP supplemental information should be viewed in addition to, not instead of, our Financial Statements.
Organic Revenue Growth
We use supplemental information related to organic revenue growth to help us and our investors evaluate business growth from existing operations. Organic revenue growth is a non-GAAP measure that includes the impact of intercompany activity and excludes the impact of the adoption of the new revenue recognition standard, changes in foreign exchange rates, acquisitions, divestitures, transfers between revenue lines, and fiduciary investment income. This supplemental information related to organic revenue growth represents a measure not in accordance with U.S. GAAP and should be viewed in addition to, not instead of, our Financial Statements. Industry peers provide similar supplemental information about their revenue performance, although they may not make identical adjustments. A reconciliation of this non-GAAP measure to the reported Total revenue is as follows (in millions, except percentages):

Adjusted Operating Margin
We use adjusted operating margin as a non-GAAP measure of core operating performance of the Company. Adjusted operating margin excludes the impact of certain items, as listed below, because management does not believe these expenses reflect our core operating performance. This supplemental information related to adjusted operating margin represents a measure not in accordance with U.S. GAAP and should be viewed in addition to, not instead of, our Financial Statements.

Adjusted Diluted Earnings per Share
We use adjusted diluted earnings per share as a non-GAAP measure of our core operating performance. Adjusted diluted earnings per share excludes the items identified above, along with pension settlements and related income taxes, because management does not believe these expenses are representative of our core earnings. This supplemental information related to adjusted diluted earnings per share represents a measure not in accordance with U.S. GAAP and should be viewed in addition to, not instead of, our Financial Statements and Notes thereto.

Free Cash Flow
We use free cash flow, defined as cash flow provided by operations less capital expenditures, as a non-GAAP measure of our core operating performance and cash-generating capabilities of our business operations. This supplemental information related to free cash flow represents a measure not in accordance with U.S. GAAP and should be viewed in addition to, not instead of, our Financial Statements. The use of this non-GAAP measure does not imply or represent the residual cash flow for discretionary expenditures. A reconciliation of this non-GAAP measure to the reported cash provided by continuing operating activities is as follows (in millions):

Impact of Foreign Exchange Rate Fluctuations
Because we conduct business in more than 100 countries, foreign exchange rate fluctuations have a significant impact on our business. Foreign exchange rate movements may be significant and may distort true period-to-period comparisons of changes in
54

revenue or pretax income. Therefore, to give financial statement users meaningful information about our operations, we have provided an illustration of the impact of foreign currency exchange rates on our financial results. The methodology used to calculate this impact isolates the impact of the change in currencies between periods by translating the prior year quarter’s revenue, expenses, and net income using the current quarter’s foreign exchange rates.
Translating prior year quarter results at current quarter foreign exchange rates, currency fluctuations had a an unfavorable impact of $0.02 and a favorable impact of $0.14, respectively, on net income per diluted share during the three and six months ended June 30, 2018. Currency fluctuations had a $0.05 impact on net income per diluted share during the three and six months ended June 30, 2017, when 2016 results were translated at 2017 rates.
Translating prior year quarter results at current quarter foreign exchange rates, currency fluctuations had no impact and a favorable impact of $0.19, respectively, on adjusted net income per diluted share during the three and six months ended June 30, 2018. Currency fluctuations had a favorable impact of $0.02 and $0.01, respectively, on adjusted net income per diluted share during the three and six months ended June 30, 2017, when 2016 results were translated at 2017 rates. These translations are performed for comparative and illustrative purposes only and do not impact the accounting policies or practices for amounts included in the Financial Statements.
Competition and Markets Authority
The U.K.’s competition regulator, the Competition and Markets Authority (the “CMA”), is conducting a market investigation into the supply and acquisition of investment consulting and fiduciary management services, including those offered by Aon and its competitors in the U.K. The CMA is assessing whether any feature or combination of features in the target market prevents, restricts, or distorts competition. The CMA issued a provisional decision report on July 18, 2018. A final decision is due to be published by March 13, 2019.
Financial Conduct Authority
The FCA is conducting a market study to assess how effectively competition is working in the wholesale insurance broker sector in the UK in which Aon, through its subsidiaries, participates. The FCA has indicated that the purpose of a market study is to assess the extent to which the market is working well in the interests of customers and to identify features of the market that may impact competition. Depending on the study’s findings, the FCA may require remedies in order to correct any features found to be preventing, restricting, or distorting competition. The study is ongoing and we are unable to estimate the impact, if any, on Aon’s business at this time.
LIQUIDITY AND FINANCIAL CONDITION
Liquidity
Executive Summary
We believe that our balance sheet and strong cash flow provide us with adequate liquidity. Our primary sources of liquidity are cash flows from operations, available cash reserves, and debt capacity available under our credit facilities. Our primary uses of liquidity are operating expenses, restructuring activities, capital expenditures, acquisitions, share repurchases, pension obligations, and shareholder dividends. We believe that cash flows from operations, available credit facilities and the capital markets will be sufficient to meet our liquidity needs, including principal and interest payments on debt obligations, capital expenditures, pension contributions, and anticipated working capital requirements, for the foreseeable future.
Cash on our balance sheet includes funds available for general corporate purposes, as well as amounts restricted as to their use. Funds held on behalf of clients in a fiduciary capacity are segregated and shown together with uncollected insurance premiums in Fiduciary assets in the Condensed Consolidated Statements of Financial Position, with a corresponding amount in Fiduciary liabilities.
In our capacity as an insurance broker or agent, we collect premiums from insureds and, after deducting our commission, remit the premiums to the respective insurance underwriter. We also collect claims or refunds from underwriters on behalf of insureds, which are then returned to the insureds. Unremitted insurance premiums and claims are held by us in a fiduciary capacity. In addition, some of our outsourcing agreements require us to hold funds on behalf of clients to pay obligations on their behalf. The levels of fiduciary assets and liabilities can fluctuate significantly, depending on when we collect premiums, claims, and refunds, make payments to underwriters and insureds, collect funds from clients and make payments on their behalf, and the movement of foreign currency exchange rates. Fiduciary assets, because of their nature, are generally invested in very liquid securities with highly-rated, credit-worthy financial institutions. In our Condensed Consolidated Statements of Financial Position, the amounts we report for Fiduciary assets and Fiduciary liabilities are equal and offsetting. Our Fiduciary assets included cash and short-term investments of $3.8 billion and $3.7 billion at June 30, 2018 and December 31, 2017, respectively, and fiduciary
55

receivables of $6.6 billion and $5.9 billion at June 30, 2018 and December 31, 2017, respectively. While we earn investment income on the fiduciary assets held in cash and investments, the cash and investments cannot be used for general corporate purposes.
We maintain multicurrency cash pools with third-party banks in which various Aon entities participate. Individual Aon entities are permitted to overdraw on their individual accounts provided the overall global balance does not fall below zero. At June 30, 2018, non-U.S. cash balances of one or more entities were negative; however, the overall balance was positive.
As of June 30, 2018, our investments in money market funds had a fair value of $1.7 billion and are reported as Short-term investments or Fiduciary assets in the Condensed Consolidated Statements of Financial Position depending on their nature.
The following table summarizes our Fiduciary assets, non-fiduciary Cash and cash equivalents, and Short-term investments as of June 30, 2018 (in millions):

Operating Activities
Net cash provided by operating activities for continuing operations during the six months ended June 30, 2018 decreased $23 million, or 5%, from the prior year period to $413 million. This amount represents net income reported, as adjusted for gains or losses on sales of businesses, share-based compensation expense, depreciation expense, amortization and impairments, and other non-cash income and expenses, as well as changes in working capital that relate primarily to the timing of payments of accounts payable and accrued liabilities and collection of receivables.
Pension Contributions
Pension contributions were $84 million for the six months ended June 30, 2018, as compared to $79 million for the six months ended June 30, 2017. For the remainder of 2018, we expect to contribute approximately $173 million in cash to our pension plans, including contributions to non-U.S. pension plans which are subject to changes in foreign exchange rates. This includes our anticipated acceleration of contributions to the qualified U.S. pension plan of approximately $100 million in the third quarter of 2018, which will allow the pension contribution tax deduction to be taken at the 2017 federal tax rate of 35%.
Restructuring Plan
In 2017, we initiated the Restructuring Plan in connection with the sale of the Divested Business. The Restructuring Plan is intended to streamline operations across the organization and deliver greater efficiency, insight, and connectivity. We expect these restructuring activities and related expenses to affect continuing operations through 2019, including an estimated 4,200 to 4,800 role eliminations. The Restructuring Plan is expected to result in cumulative costs of approximately $1,025 million through the end of the plan, consisting of approximately $420 million in employee termination costs, $130 million in technology rationalization costs, $60 million in real estate consolidation costs, $40 million in non-cash asset impairments, and $375 million in other costs
56

including certain separation costs associated with the sale of the Divested Business. We estimate that our annualized savings from the Restructuring Plan will be approximately $450 million by the end of 2019.
From the inception of the Restructuring Plan through June 30, 2018, the Company has eliminated 3,337 positions and a total of $766 million of restructuring and related separation charges have been incurred. These charges are included in Compensation and benefits, Information technology, Premises, Depreciation of fixed assets, and Other general expenses in the accompanying Condensed Consolidated Statements of Income.
The following summarizes restructuring and separation costs by type that have been incurred through June 30, 2018 and are estimated to be incurred through the end of the Restructuring Plan. Estimated costs may be revised in future periods as these assumptions are updated (in millions):

|  | Three months ended June 30, 2018 |  | Six months ended June 30, 2018 |  | Inception to Date |  | Estimated Remaining Costs |  | Estimated Total Cost (1)
Workforce reduction |  | $ | 33 |  |  | $ | 66 |  |  | $ | 365 |  |  | $ | 55 |  |  | $ | 420 |

Other costs associated with restructuring and separation (2) (3) |  | 136 |  |  | 163 |  |  | 294 |  |  | 81 |  |  | 375 |
Total restructuring and related expenses |  | $ | 195 |  |  | $ | 269 |  |  | $ | 766 |  |  | $ | 259 |  |  | $ | 1,025 |

(1) | Actual costs, when incurred, may vary due to changes in the assumptions built into the Restructuring Plan. Significant assumptions that may change when plans are finalized and implemented include, but are not limited to, changes in severance calculations, changes in the assumptions underlying sublease loss calculations due to changing market conditions, and changes in the overall analysis that might cause the Company to add or cancel component initiatives.

(2) | Total contract termination costs incurred under the Restructuring Plan associated with Technology rationalizations, Lease consolidations, and Other costs associated with restructuring and separation, respectively, for the three months ended June 30, 2018 were $0 million, $10 million, and $75 million; for the six months ended June 30, 2018 were $1 million, $12 million, and $79 million; and since inception of the Restructuring Plan were $2 million, $20 million, and $82 million. Total estimated contract termination costs expected to be incurred under the Restructuring Plan associated with Technology rationalizations, Lease consolidations, and Other costs associated with restructuring and separation, respectively, are $15 million, $80 million, and $82 million.

(3) | Other costs associated with the Restructuring Plan include those to separate the Divested Business, as well as moving costs and consulting and legal fees. These costs are generally recognized when incurred.

As of June 30, 2018, the changes in our liabilities for the Restructuring Plan were as follows (in millions):

|  | Restructuring Plan
Balance as of December 31, 2017 |  | $ | 186 |
Expensed |  | 260 |
Cash payments |  | (248 | )
Foreign currency translation and other |  | (2 | )
Balance as of June 30, 2018 |  | $ | 196 |

Investing Activities
Cash flow provided by investing activities in continuing operations was $179 million during the six months ended June 30, 2018, a decrease of $1,329 million compared to prior year period. The primary drivers of cash flow used for investing activities are acquisition of businesses, purchases of short-term investments, capital expenditures, and payments for investments. The primary drivers of cash flow provided by investing activities are sales of businesses, sales of short-term investments, and proceeds from investments. The gains and losses corresponding to cash flows provided by proceeds from investments and used for payments for investments are primarily recognized in Other income (expense) in the Condensed Consolidated Statements of Income.
Short-term Investments
Short-term investments decreased $356 million as compared to December 31, 2017. As disclosed in Note 16 “Fair Value Measurements and Financial Instruments” of the Financial Statements contained in Part I, Item 1 of this report, the majority of our investments carried at fair value are money market funds. These money market funds are held throughout the world with various financial institutions. We are not aware of any market liquidity issues that would materially impact the fair value of these investments.

Acquisitions and Dispositions of Businesses
During the first six months of 2018, the Company completed the acquisition of five businesses for a total consideration of $59 million and one business was sold for an insignificant amount.
During the first six months of 2017, the Company completed the acquisition of four businesses for a total consideration of $176 million and the sale of four businesses for a net cash outflow of $2 million due to an excess of cash sold, excluding the sale of the Divested Business.
Capital Expenditures
The Company’s additions to fixed assets, including capitalized software, which amounted to $111 million in 2018 and $82 million in 2017, primarily relate to computer equipment purchases, the refurbishing and modernizing of office facilities, and software development costs.
Financing Activities
Cash flow used for financing activities in continuing operations during the six months ended June 30, 2018 was $798 million, a decrease of $972 million compared to prior year period. The primary drivers of cash flow used for financing activities are share repurchases, issuances of debt, net of repayments, dividends paid to shareholders, issuances of shares for employee benefit plans, transactions with noncontrolling interests, and other financing activities, such as collection of or payments for deferred consideration in connection with prior-year business acquisitions and divestitures.
Share Repurchase Program
Aon has a share repurchase program authorized by the Company’s Board of Directors. The Repurchase Program was established in April 2012 with up to $5.0 billion in authorized repurchases, and was increased by $5.0 billion in authorized repurchases in each of November 2014 and February 2017 for a total of $15.0 billion in repurchase authorizations.
The following table summarizes the Company’s Share Repurchase activity (in millions, except per share data):

| Three months ended June 30 |  | Six months ended June 30
| 2018 |  | 2017 (1) |  | 2018 |  | 2017 (1)
Shares repurchased | 2.8 |  |  | 8.0 |  |  | 6.7 |  |  | 9.1 |
Average price per share | $ | 141 |  |  | $ | 129 |  |  | $ | 141 |  |  | $ | 127 |
Costs recorded to retained earnings: |  |  |  |  |  |  |
Total repurchase cost | $ | 400 |  |  | $ | 1,030 |  |  | $ | 950 |  |  | $ | 1,154 |
Additional associated costs | 2 |  |  | 5 |  |  | 5 |  |  | 6 |
Total costs recorded to retained earnings | $ | 402 |  |  | $ | 1,035 |  |  | $ | 955 |  |  | $ | 1,160 |

(1) | Included in the 8.0 million shares and 9.1 million shares repurchased during the three and six months ended June 30, 2017, respectively, were 0.5 million shares that did not settle until July 2017. These shares were settled at an average price per share of $133.24 and total cost of $60 million.

At June 30, 2018, the remaining authorized amount for share repurchase under the Repurchase Program is approximately $4.5 billion. Under the Repurchase Program, we have repurchased a total of 115.0 million shares for an aggregate cost of approximately $10.5 billion. For further information regarding share repurchases made during the second quarter of 2018, see Part II, Item 2 of this report.
Borrowings
Total debt at June 30, 2018 was $6.5 billion, an increase of $492 million compared to December 31, 2017. On March 8, 2018, the Company’s CAD 375 million ($291 million at March 8, 2018 Exchange Rates) 4.76% Senior Note due March 2018 issued by a Canadian subsidiary of Aon Corporation matured and were repaid in full. Further, commercial paper activity during the three and six months ended June 30, 2018 and 2017 is as follows (in millions):
58

|  | Three months ended June 30 |  | Six months ended June 30
|  | 2018 |  | 2017 |  | 2018 |  | 2017
Total issuances (1) |  | $ | 1,746 |  |  | $ | 654 |  |  | $ | 2,551 |  |  | $ | 1,648 |
Total repayments |  | $ | (1,321 | ) |  | $ | (1,050 | ) |  | $ | (1,732 | ) |  | $ | (1,997 | )
Net issuances |  | $ | 425 |  |  | $ | (396 | ) |  | $ | 819 |  |  | $ | (349 | )

(1) | The proceeds of the commercial paper issuances were used primarily for short-term working capital needs.

Other Liquidity Matters
Distributable Reserves
As a company incorporated in England and Wales, we are required under U.K. law to have available “distributable reserves” to make share repurchases or pay dividends to shareholders. Distributable reserves are created through the earnings of the U.K. parent company. Distributable reserves are not linked to a U.S. GAAP reported amount (e.g., retained earnings). As of June 30, 2018 and December 31, 2017, we had distributable reserves in excess of $2.9 billion and $1.2 billion, respectively. We believe that we will have sufficient distributable reserves to fund shareholder dividends, if and to the extent declared, for the foreseeable future.
Credit Facilities
We expect cash generated by operations for 2018 to be sufficient to service our debt and contractual obligations, finance capital expenditures, continue purchases of shares under the Repurchase Program, and continue to pay dividends to our shareholders. Although cash from operations is expected to be sufficient to service these activities, we have the ability to access the commercial paper markets or borrow under our credit facilities to accommodate any timing differences in cash flows. Additionally, under current market conditions, we believe that we could access capital markets to obtain debt financing for longer-term funding, if needed.
As of June 30, 2018, we had two committed credit facilities outstanding: our $900 million multi-currency U.S. credit facility expiring in February 2021 and our $400 million multi-currency U.S. credit facility expiring in October 2022.
Each of these facilities includes customary representations, warranties, and covenants, including financial covenants that require us to maintain specified ratios of adjusted consolidated EBITDA to consolidated interest expense and consolidated debt to consolidated adjusted EBITDA, tested quarterly. At June 30, 2018, we did not have borrowings under either the 2021 or the 2022 Facility, and we were in compliance with the financial covenants and all other covenants contained therein during the rolling twelve months ended June 30, 2018.
Shelf Registration Statement
On September 3, 2015, we filed a shelf registration statement with the SEC, registering the offer and sale from time to time of an indeterminate amount of, among other securities, debt securities, preference shares, Class A Ordinary Shares and convertible securities. Our ability to access the market as a source of liquidity is dependent on investor demand, market conditions, and other factors.
Rating Agency Ratings
The major rating agencies’ ratings of our debt at July 27, 2018 appear in the table below.

| Ratings |  |
| Senior Long-term Debt |  | Commercial Paper |  | Outlook
Standard & Poor’s | A- |  | A-2 |  | Stable
Moody’s Investor Services | Baa2 |  | P-2 |  | Stable
Fitch, Inc. | BBB+ |  | F-2 |  | Stable

A downgrade in the credit ratings of our senior debt or commercial paper could increase our borrowing costs, reduce or eliminate our access to capital, reduce our financial flexibility, restrict our access to the commercial paper market altogether, or impact future pension contribution requirements.
Guarantees in Connection with the Sale of the Divested Business
59

In connection with the sale of the Divested Business, we guaranteed future operating lease commitments related to certain facilities assumed by the Buyer. We are obligated to perform under the guarantees if the Divested Business defaults on the leases at any time during the remainder of the lease agreements, which expire on various dates through 2024. As of June 30, 2018, the undiscounted maximum potential future payments under the lease guarantee were $93 million, with an estimated fair value of $20 million. No cash payments were made in connection to the lease commitments during the three months ended June 30, 2018.
Additionally, we are subject to performance guarantee requirements under certain client arrangements that were assumed by the Buyer. Should the Divested Business fail to perform as required by the terms of the arrangements, we would be required to fulfill the remaining contract terms, which expire on various dates through 2023. As of June 30, 2018, the undiscounted maximum potential future payments under the performance guarantees were $200 million, with an estimated fair value of $1 million. No cash payments were made in connection to the performance guarantees during the three months ended June 30, 2018.
Letters of Credit and Other Guarantees
We have entered into a number of arrangements whereby our performance on certain obligations is guaranteed by a third party through the issuance of a letter of credit. We had total LOCs outstanding of approximately $93 million at June 30, 2018, compared to $96 million at December 31, 2017. These LOCs cover the beneficiaries related to certain of our U.S. and Canadian non-qualified pension plan schemes and secure deductible retentions for our own workers compensation program. We also have obtained LOCs to cover contingent payments for taxes and other business obligations to third parties, and other guarantees for miscellaneous purposes at our international subsidiaries.
We have certain contractual contingent guarantees for premium payments owed by clients to certain insurance companies. The maximum exposure with respect to such contractual contingent guarantees was approximately $89 million at June 30, 2018, compared to $95 million at December 31, 2017.
Off-Balance Sheet Arrangements
Apart from commitments, guarantees, and contingencies, as disclosed herein and Note 17 “Commitments and Contingencies” to the Financial Statements, the Company had no off-balance sheet arrangements that have, or are reasonably likely to have, a current or future material effect on the Company’s financial condition, results of operations, or liquidity. Our cash flows from operations, borrowing availability, and overall liquidity are subject to risks and uncertainties. See “Information Concerning Forward-Looking Statements” below.
CRITICAL ACCOUNTING POLICIES AND ESTIMATES
There have been no changes in our critical accounting policies, which include pensions, goodwill and other intangible assets, contingencies, share-based payments, and income taxes, as discussed in our Annual Report on Form 10-K for the year ended December 31, 2017 (our “2017 Annual Report on Form 10-K”) other than those described below.
Revenue Recognition
The Company recognizes revenue when control of the promised services are transferred to the customer in the amount that best reflects the consideration to which the Company expects to be entitled in exchange for those services. For arrangements where control is transferred over time, an input or output method is applied that represents a faithful depiction of the progress towards completion of the performance obligation. For arrangements that include variable consideration, the Company assesses whether any amounts should be constrained. For arrangements that include multiple performance obligations, the Company allocates consideration based on their relative fair values.
Costs incurred by the Company in obtaining a contract are capitalized and amortized on a systematic basis that is consistent with the transfer of the services to which the asset relates, considering anticipated renewals when applicable. Certain contract related costs, including pre-placement brokerage costs, are capitalized as a cost to fulfill and are amortized on a systematic basis consistent with the transfer of services to which the asset relates, which is generally less than one year.
Commercial Risk Solutions includes retail brokerage, cyber solutions, global risk consulting, and captives. Revenue primarily includes insurance commissions and fees for services rendered. Revenues will generally be recognized at a point in time upon the effective date of the underlying policy or over the term of the arrangement to depict the transfer of control of the services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Revenues are recorded net of allowances for estimated policy cancellations, which are determined based on an evaluation of historical and current cancellation data.
60

Reinsurance Solutions includes treaty and facultative reinsurance brokerage and capital markets. Revenue primarily includes reinsurance commissions and fees for services rendered. Revenues will generally be recognized at a point in time upon the effective date of the underlying policy or over the term of the arrangement to depict the transfer of control of services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.
Retirement Solutions includes core retirement, investment consulting, and talent, rewards & performance. Revenue consists primarily of fees paid by clients for consulting services, such as risk management strategies, health and benefits, and human capital consulting services. Revenue recognized for these arrangements are typically recognized at a point-in-time upon completion of the service or over-time to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. For consulting arrangements recognized over-time, revenue will be recognized based on a measure of progress that depicts the transfer of control of the goods or services to the customer, utilizing an appropriate input or output measure. Fees paid by clients for consulting services are typically charged on an hourly, project or fixed-fee basis. Revenues from time-and-materials or cost-plus arrangements are recognized as services are performed. Reimbursements received for out-of-pocket expenses are recorded as a component of revenue.
Health Solutions includes health and benefits brokerage and healthcare exchanges. Revenue primarily includes insurance commissions and fees for services rendered. For brokerage commissions, revenue is typically recognized at the effective date of the underlying policy or over the term of the arrangement to depict the transfer of control of the services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those services. Revenues from health care exchange arrangements are typically recognized upon successful enrollment of participants, net of a reserve for estimated cancellations.
Data & Analytic Services includes Affinity, Aon InPoint, and ReView. Revenue consists primarily of fees for services rendered and is generally recognized over the term of the arrangement to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. For Data & Analytic Services arrangements recognized over-time, revenue will be recognized based on a measure of progress that depicts the transfer of control of the goods or services to the customer, utilizing an appropriate input or output measure.
NEW ACCOUNTING PRONOUNCEMENTS
Note 2 “Accounting Principles and Practices” to the Financial Statements contained in Part I, Item 1 of this report contains a discussion of recently issued accounting pronouncements and their impact or future potential impact on our financial results, if determinable.
INFORMATION CONCERNING FORWARD-LOOKING STATEMENTS
This report and reports we will subsequently file or furnish and have previously filed or furnished with the SEC contains certain statements related to future results, or states 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 use words such as “anticipate,” “believe,” “estimate,” “expect,” “forecast,” “project,” “intend,” “plan,” “probably,” “potential,” “looking forward,” 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; 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 revenue; 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; and the impact of changes in accounting rules. These 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 different countries in which we do business around the world;

• | changes in the competitive environment;

• | 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;

61

• | 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 U.S. federal income tax reform;

• | the effect of the change in global headquarters and jurisdiction of incorporation, including differences in the anticipated benefits;

• | 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 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 English 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 effect of natural or man-made disasters;

• | 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;

• | our risks and uncertainties in connection with the sale, including arrangements under the transition service agreement and legacy IT systems associated with the Divested Business; and

• | our ability to realize the expected benefits from our restructuring plan.

62

Any or all of our forward-looking statements may turn out to be inaccurate, and there are no guarantees about our performance. The factors identified above are not exhaustive. Aon and its subsidiaries operate in a dynamic business environment in which new risks may emerge frequently. Accordingly, readers should not place undue reliance on forward-looking statements, which speak only as of the dates on which they are made. We are under no obligation (and expressly disclaim any obligation) to update or alter any forward-looking statement that we may make from time to time, whether as a result of new information, future events or otherwise. Further information about factors that could materially affect Aon, including our results of operations and financial condition, is contained in Part III, Item 1A Risk Factors of this report and in the “Risk Factors” section in Part I, “Item 1A Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2017. These factors may be revised or supplemented in subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K.
Item 3. Quantitative and Qualitative Disclosures about Market Risk
We are exposed to potential fluctuations in earnings, cash flows and the fair value of certain of our assets and liabilities due to changes in interest rates and foreign exchange rates. To manage the risk from these exposures, we enter into a variety of derivative instruments. We do not enter into derivatives or financial instruments for trading or speculative purposes.
The following discussion describes our specific exposures and the strategies we use to manage these risks. There have been no changes in our critical accounting policies for financial instruments and derivatives as discussed in our 2017 Annual Report on Form 10-K.
Foreign Exchange Risk
We are subject to foreign exchange rate risk. Our primary exposures include exchange rates between the U.S. Dollar and the Euro, the British Pound, the Canadian Dollar, the Australian Dollar, the Indian Rupee, and the Japanese Yen. We use over-the-counter options and forward contracts to reduce the impact of foreign currency risk to our financial statements.
Additionally, some of our non-U.S. brokerage subsidiaries receive revenue in currencies that differ from their functional currencies. Our U.K. subsidiaries earn a portion of their revenue in U.S. Dollars, Euro, and Japanese Yen, but most of their expenses are incurred in British Pounds. At June 30, 2018, we have hedged approximately 45% of our U.K. subsidiaries’ expected exposures to U.S. Dollar, Euro, and Japanese Yen transactions for the years ending December 31, 2018 and 2019, respectively. We generally do not hedge exposures beyond three years.
We also use forward and option contracts to economically hedge foreign exchange risk associated with monetary balance sheet exposures, such as inter-company notes and short-term assets and liabilities that are denominated in a non-functional currency and are subject to remeasurement.
The translated value of revenue and expense from our international brokerage operations are subject to fluctuations in foreign exchange rates. If we were to translate prior year results at current quarter exchange rates, diluted earnings per share would decrease by $0.02 and increase by $0.14, respectively, during the three and six months ended June 30, 2018. Further, adjusted diluted earnings per share, a non-GAAP measure as defined and reconciled under the caption “Review of Consolidated Results — Adjusted Diluted Earnings Per Share,” would have no impact and increase by $0.19, respectively, during the three and six months ended June 30, 2018 if we were to translate prior year results at current quarter exchange rates.
Effective July 1, 2018, Argentina was designated as a highly inflationary economy and therefore the functional currency for our Argentina subsidiaries became the U.S. dollar. As a result, the impact of Argentine peso currency fluctuations in these subsidiaries will be reported within the Condensed Consolidated Statement of Income prospectively. We are undergoing steps to limit this exposure, and do not expect a material impact to be to the Financial Statements. Revenue from our Argentine operations was less than 1 % of our consolidated revenue for the three and six months ended June 30, 2018 and 2017.
Interest Rate Risk
Our fiduciary investment income is affected by changes in international and domestic short-term interest rates. We monitor our net exposure to short-term interest rates and, as appropriate, hedge our exposure with various derivative financial instruments. This activity primarily relates to brokerage funds held on behalf of clients in the U.S. and in continental Europe. A decrease in global short-term interest rates adversely affects our fiduciary investment income.
Item 4. Controls and Procedures
Evaluation of disclosure controls and procedures. We have conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as of the end of the period covered by this quarterly report of June 30, 2018. Based on this evaluation, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures were effective such that the information relating to Aon, including our consolidated subsidiaries, required to be disclosed in our
63

SEC reports is recorded, processed, summarized and reported within the time periods specified in appropriate statute, SEC rules and forms, and is accumulated and communicated to Aon’s management, including our chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.
Changes in internal control over financial reporting. No changes in Aon’s internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) occurred during the quarter ended June 30, 2018 that have materially affected, or that are reasonably likely to materially affect, Aon’s internal control over financial reporting.
