Notes to Condensed Consolidated Financial Statements (Unaudited)

1. Basis of Presentation

The accompanying unaudited Condensed Consolidated Financial Statements and Notes thereto have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). The Condensed Consolidated 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 Condensed Consolidated 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 Condensed Consolidated 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, 2016. The results for the three and nine months ended September 30, 2017 are not necessarily indicative of operating results that may be expected for the full year ending December 31, 2017.

Discontinued Operations

On February 9, 2017, the Company entered into a Purchase Agreement (the “Purchase Agreement”) with Tempo Acquisition, LLC (the “Buyer”), an entity formed and controlled by affiliates of The Blackstone Group L.P. Pursuant to the Purchase Agreement, the Company sold its benefits administration and business process outsourcing business (the “Divested Business”) to the Buyer and certain designated purchasers that are direct or indirect subsidiaries of the Buyer (the “Transaction”). As a result, the Divested Business’s financial results are reflected in the Condensed Consolidated Statements of Income, Condensed Consolidated Statements of Financial Position, and Condensed Consolidated Statements of Cash Flows, retrospectively, as discontinued operations beginning in the first quarter of 2017. Additionally, all of the Notes to Condensed Consolidated Financial Statements have been retrospectively restated to only include the impacts of continuing operations, unless noted otherwise. The Transaction closed on May 1, 2017. Refer to Note 3 “Discontinued Operations” for additional information.

Reportable Segments

Beginning in the first quarter of 2017, the Company began operating as one segment that includes all of Aon’s continuing operations, which provides advice and solutions to clients focused on risk, retirement, and health through five revenue lines that make up our principal products and services. Refer to Note 17 “Segment Information” for additional information.

As a result of these initiatives, Aon made the following changes to its presentation of the Condensed Consolidated Statement of Income beginning in the first quarter of 2017:


•	Commissions, fees and other and Fiduciary investment income are now reported as one Total revenue line item; and


•	Other general expenses has been further broken out to provide greater clarity into charges related to Information technology, Premises, Depreciation of fixed assets, and Amortization and impairment of intangible assets.

Prior period comparable financial information has been reclassified to conform to this presentation.

The Company believes this presentation provides greater clarity into the risks and opportunities that management believes are important and allows users of the financial statements to assess the performance in the same way as the Chief Operating Decision Maker (the “CODM”).

Use of Estimates

The preparation of the accompanying Condensed Consolidated 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

Share-based Compensation

In March 2016, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance on several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The new guidance requires all excess tax benefits and tax deficiencies to be recognized as income tax expense or benefit in the income statement and treated as discrete items in the reporting period. Further, excess tax benefits are required to be classified along with other income tax cash flows as an operating activity. Amendments related to the timing of when excess tax benefits are recognized, minimum statutory withholding requirements, forfeitures, and intrinsic value should be applied using a modified retrospective transition method by means of a cumulative-effect adjustment to equity as of the beginning of the period in which the guidance is adopted. Amendments related to the presentation of employee taxes paid on the statement of cash flows when an employer withholds shares to meet the minimum statutory withholding requirement should be applied retrospectively. Amendments requiring recognition of excess tax benefits and tax deficiencies in the income statement and the practical expedient for estimating expected term should be applied prospectively. An entity may elect to apply the amendments related to the presentation of excess tax benefits on the statement of cash flows using either a prospective transition method or a retrospective transition method.

The Company adopted this guidance on January 1, 2017, with the following impacts:


•	An increase to Deferred tax assets on the Condensed Consolidated Statement of Financial Position of approximately $49 million through a cumulative-effect adjustment to Retained earnings for excess tax benefits not previously recognized, and


•	The recognition of $5 million, or $0.02 per share, income tax benefit from continuing operations related to excess tax benefits in the Condensed Consolidated Statement of Income for the three months ended September 30, 2017, and $53 million, or $0.20 per share, for the nine months ended September 30, 2017.

Adoption of the guidance was applied prospectively on the Condensed Consolidated Statement of Cash Flows and prior period comparable information was not restated. Other elements of the guidance did not have a material impact on the Company’s Condensed Consolidated Financial Statements.

Accounting Standards Issued But Not Yet Adopted

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 Condensed Consolidated Financial Statements and the period in which it plans to adopt.

Presentation of Net Periodic Pension and Postretirement Benefit Costs

In March 2017, the 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. An entity will apply 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 new guidance is effective for Aon in the first quarter of 2018. The adoption of this

guidance will have no impact on the total results of the Company. The presentation of results will reflect a change in Operating income offset by an equal change in Other income (expense) for the period.

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 for annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the period of adoption and the impact that the standard will have on the Condensed Consolidated Financial Statements.

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 will require 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). An entity will apply 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 is effective for Aon in the first quarter of 2018, and the Company is currently evaluating the impact that the standard will have on the Condensed Consolidated Financial Statements.

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 will no longer have 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 will be effective for the Company in the first quarter of 2018, with early adoption permitted. An entity will apply the new guidance through retrospective adjustment to all periods presented. The retrospective approach includes a practical expedient that entities may apply should retrospective adoption be impracticable; in this case, the amendments for these issues may be applied prospectively as of the earliest date practicable. The guidance will not have a material impact on the Company’s Condensed Consolidated Statements of Cash Flows.

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 the Condensed Consolidated Financial Statements, as well as the method of transition and period of adoption.

Leases

In February 2016, the FASB issued new accounting guidance on leases, which requires lessees to recognize assets and liabilities for most leases. Under the new guidance, 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 currently effective U.S. GAAP. The new standard will be effective for the Company in the first quarter of 2019, 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. Aon is currently evaluating the impact the standard will have on the Condensed Consolidated Financial Statements and period of adoption.

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. An entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values, including disclosure requirements, should be applied prospectively to equity investments that exist as of the date of adoption of the guidance. The guidance is effective for the Company in the first quarter of 2018 and early adoption is permitted. Aon is currently evaluating the impact that the standard will have on the Condensed Consolidated Financial Statements and period of adoption.

Revenue Recognition

In May 2014, the FASB issued a new accounting standard on revenue from contracts with customers, which, when effective, will supersede nearly all existing revenue recognition guidance under U.S. GAAP. 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 and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The standard is effective for Aon in the first quarter of 2018 and early adoption is permitted beginning in the first quarter of 2017. Two methods of transition are permitted upon adoption: full retrospective and modified retrospective. Under the full retrospective method, prior periods would be restated under the new revenue standard, providing a comparable view across all periods presented. Under the modified retrospective method, prior periods would not be restated. Rather, revenue and other disclosures for pre-2018 periods would be provided in the notes to the financial statements as previously reported under the current revenue standard. The Company will adopt this standard in the first quarter of 2018 using a modified retrospective adoption approach.

A preliminary assessment to determine the impacts of the new accounting standard has been performed. The Company is currently implementing accounting and operational processes and controls to ensure compliance with the new standard, but is still evaluating the quantitative impacts the standard will have on its financial statements.

However, the more significant impacts of the new standard to the Company are anticipated to be as follows:

The Company currently recognizes 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 becomes determinable. Under the new standard, the revenue related to certain brokerage activities recognized over a period of time will be 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 will be recognized in earlier periods under the new standard in comparison to the current guidance and will change the timing and amount of revenue recognized for annual and interim periods. This change is anticipated to result in a significant shift in interim revenue for Reinsurance Solutions and certain other brokerage services. The Company is currently assessing the timing and measurement of revenue recognition under the new standard for certain other services, including advisory, where limited impacts are anticipated.

Additionally, the new 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 are currently expensed as incurred under existing U.S. GAAP. 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 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 plans to apply a practical expedient and recognize the costs of obtaining a contract as an expense when incurred. Assets recognized for the costs to fulfill a contract, which includes internal costs related to pre-placement broking activities, will be amortized on a systematic basis that is consistent with the transfer of the services to which the asset relates, which is generally expected to be less than one year. The Company is quantifying the nature and amount of costs that would qualify for capitalization and the amount of amortization that will be recognized in each period.

3. Discontinued Operations

On February 9, 2017, the Company entered into the Purchase Agreement with Tempo Acquisition, LLC to sell its benefits administration and business process outsourcing business to the Buyer, an entity formed and controlled by affiliates of The Blackstone Group L.P., 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. 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.

In the nine months ended September 30, 2017, the Company recorded an estimated gain on sale, net of taxes, of $803 million and a non-cash impairment charge to its tradenames associated with the Divested Business of $380 million as these assets were not sold to the Buyer. The impairment charge is included in Amortization and impairment of intangible assets on the Condensed Consolidated Statement of Income for the nine months ended September 30, 2017.

The Company has classified the results of the Divested Business as discontinued operations in the Company’s Condensed Consolidated Statements of Income for all periods presented.

7. 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 2,400 to 2,850 role eliminations. The Restructuring Plan is expected to result in cumulative costs of approximately $750 million through the end of the plan, consisting of approximately $303 million in employee termination costs, $146 million in technology rationalization costs, $80 million in lease consolidation costs, $40 million in asset impairments, and $181 million in other costs, including certain separation costs associated with the sale of the Divested Business. Included in the estimated $750 million are $50 million of non-cash charges related to asset impairments and lease consolidations.

From the inception of the Restructuring Plan through September 30, 2017, the Company has eliminated 2,125 positions and incurred total expenses of $401 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 September 30, 2017 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 September 30, 2017		Nine months ended September 30, 2017		Estimated Remaining Costs		Estimated Total Cost ⁽¹⁾
Workforce reduction	$	52	$	257	$	46	$	303

Lease consolidation ⁽²⁾	4		8		72		80
Asset impairments	2		26		14		40
Other costs associated with restructuring and separation ^{(2) (3)}	32		88		93		181
Total restructuring and related expenses	$	102	$	401	$	349	$	750

(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)

Contract termination costs included within Technology rationalization for the three and nine months ended September 30, 2017 were $1 million. Contract termination costs included within Lease consolidations for the three and nine months ended September 30, 2017 were $3 million and $8 million, respectively. Contract termination costs included within Other costs associated with restructuring and separation were $1 million for the three and nine months ended September 30, 2017. Total estimated contract termination costs to be incurred under the Restructuring Plan associated with Technology rationalizations, Lease consolidations, and Other costs associated with restructuring and separation, respectively, are $10 million, $80 million, and $10 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.

The changes in the Company’s liabilities for the Restructuring Plan as of September 30, 2017 are as follows (in millions):



	Restructuring Plan
Balance as of December 31, 2016	$	—

Total	$	3,529	$	2,188	$	1,341	$	3,397	$	1,507	$	1,890


(1)	Prior to May 1, 2017, finite lived tradenames were classified within Technology and other. As of December 31, 2016, $29 million of gross carrying amount and $7 million of accumulated amortization related to finite-lived tradenames was reclassified from Technology and other to Tradenames.

In the second quarter of 2017 and in connection with the completion of the sale of the Divested Business, the Company recognized a non-cash impairment charge to the associated tradenames of $380 million. The fair value of the tradenames was determined using the Relief from Royalty Method. This impairment was included in Amortization and impairment of intangible assets on the Condensed Consolidated Statement of Income. Refer to Note 3 “Discontinued Operations” for further information.

Additionally, effective May 1, 2017 and consistent with operating as one segment, the Company implemented a three-year strategy to transition to a unified Aon brand. As a result, Aon commenced amortization of all indefinite lived tradenames and prospectively accelerated amortization of its finite-lived tradenames over the three-year period. The change in estimated useful life resulted in additional amortization expense, net of tax, to continuing operations of $34 million, or $0.13 per share, and $56 million, or $0.21 per share, in the three and nine months ended September 30, 2017, respectively.

Amortization expense and impairment charges from finite lived intangible assets was $101 million and $604 million for the three and nine months ended September 30, 2017, respectively. Amortization expense from finite lived intangible assets was $42 million and $117 million for the three and nine months ended September 30, 2016, respectively.

The estimated future amortization for finite lived intangible assets as of September 30, 2017 is as follows (in millions):



Remainder of 2017	$	117
2018	376
2019	357
2020	196

9. Debt

Notes

During the first quarter of 2017, the CAD 375 million ($304 million at September 30, 2017 exchange rates) 4.76% Senior Notes due March 2018 were classified as Short-term debt and current portion of long-term debt in the Condensed Consolidated Statements of Financial Position as the date of maturity is less than one year.

Revolving Credit Facilities

As of September 30, 2017, Aon had one primary committed credit facility outstanding: its $900 million multi-currency U.S. credit facility expiring in February 2021 (the “2021 Facility”). On October 19, 2017, Aon entered into a $400 million multi-currency U.S. credit facility expiring in October 2022 (the “2022 Facility”). This facility replaced the Company’s previous $400 million U.S. credit facility that expired in March 2017.

The 2021 Facility 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 September 30, 2017, Aon did not have borrowings under the 2021 Facility, and was in compliance with all covenants contained therein during the nine months ended September 30, 2017.

Commercial Paper

Aon Corporation, a wholly-owned subsidiary of Aon plc, has established a U.S. commercial paper program and a European multi-currency commercial paper program (collectively the “CP Programs”). Commercial paper may be issued in an aggregate principal amount of up to $1.3 billion under the CP Programs, allocated between the two programs as determined by management, not to exceed the amount of committed credit, which was $900 million at September 30, 2017. 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	September 30, 2017		December 31, 2016

10. Income Taxes

The effective tax rate on net income from continuing operations was 2.0% and (49.8)% for the three and nine months ended September 30, 2017, respectively. The effective tax rate on net income from continuing operations was 8.1% and 12.8% for the three and nine months ended September 30, 2016, respectively. For the three months ended September 30, 2017, the Company reported tax expense of $4 million on pretax income of $200 million, which resulted in an effective tax rate of 2.0%, primarily driven by the jurisdictional distribution of income including the estimated impact of the Restructuring Program and the accelerated amortization of tradenames. For the nine months ended September 30, 2017, the Company reported a tax benefit of $139 million on pretax income of $279 million, which resulted in an effective tax rate of (49.8)%. The primary components of the year to date tax amounts were the non-cash tax benefit from the tradename impairment associated with the Divested Business and the impact of share-based payments from adoption of the new share-based compensation guidance. Refer to Note 2 “Accounting Principles and Practices” for additional details.

11. Shareholders’ Equity

Ordinary Shares

Aon has a share repurchase program authorized by the Company’s Board of Directors (the “Repurchase Program”) .

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 obligation to them. A non-cash settlement charge is expected in the fourth quarter of 2017.

Contributions

The Company expects to make cash contributions of approximately $80 million, $51 million, and $18 million, based on exchange rates as of December 31, 2016, to its significant U.K., U.S., and other significant international pension plans, respectively, during 2017. During the three months ended September 30, 2017, cash contributions of $22 million, $5 million, and $3 million were made to the Company’s significant U.K., U.S., and other significant international pension plans, respectively. During the nine months ended September 30, 2017, cash contributions of $64 million, $31 million, and $14 million were made to the Company’s significant U.K., U.S., and other significant international pension plans, respectively. During the three and nine months ended September 30, 2017, Aon made a non-cash contribution of approximately $80 million to its U.S. pension plan.

During the three months ended September 30, 2016, cash contributions of $19 million, $5 million, and $4 million were made to the Company’s significant U.K., U.S., and other significant international pension plans, respectively. During the nine months ended September 30, 2016, cash contributions of $53 million, $24 million, and $14 million were made to the Company’s significant U.K., U.S., and other significant international pension plans, respectively.

13. 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 September 30				Nine months ended September 30
	2017		2016		2017		2016
Restricted share units (“RSUs”)	$	42	$	40	$	143	$	136
Performance share awards (“PSAs”)	22		24		63		67
Employee share purchase plans	3		2		8		7
Total share-based compensation expense	$	67	$	66	$	214	$	210

Restricted Share Units

RSUs generally vest between three and five years. The fair value of RSUs is based upon the market value of Aon 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 (shares in thousands):



	2017				2016
	Shares		Fair Value ⁽¹⁾		Shares		Fair Value ⁽¹⁾
Non-vested at December 31	6,195		$	89	7,167		$	77
Granted	1,549		122		2,110		101
Vested	(2,294	)	82		(2,729	)	70
Forfeited	(590	)	92		(333	)	81
Non-vested at September 30	4,860		$	102	6,215		$	88


(1)	Represents per share weighted average fair value of award at date of grant.

Unamortized deferred compensation expense amounted to $367 million as of September 30, 2017, 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 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 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 expense, if necessary. Dividend equivalents are not paid on PSAs.

Information as of September 30, 2017 regarding the Company’s target PSAs granted and shares that would be issued at current performance levels for PSAs granted during the nine months ended September 30, 2017 and the years ended December 31, 2016 and 2015, respectively, is as follows (shares in thousands and dollars in millions, except fair value):



	September 30, 2017		December 31, 2016		December 31, 2015
Target PSAs granted during period	548		752		967
Weighted average fair value per share at date of grant	$	114	$	100	$	96
Number of shares that would be issued based on current performance levels	544		663		1,362
Unamortized expense, based on current performance levels	$	51	$	27	$	11

14. 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 denominated in a currency that differs from its functional currency, or enters into other transactions that are denominated in a currency other than 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				Derivative Assets ⁽¹⁾				Derivative Liabilities ⁽²⁾

The amounts of derivative gains (losses) recognized in the Condensed Consolidated Financial Statements for the three and nine months ended September 30, 2017 and 2016 are as follows (in millions):



Cash Flow Hedge - Foreign Exchange Contracts	Location of Eventual Reclassification from Accumulated Other Comprehensive Loss										Gain (Loss) Currently Recognized in Accumulated Other Comprehensive Loss

2016	2		(2		)	(1		)	(5		)	(6		)

The Company estimates that approximately $11 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 nine months ended September 30, 2017 and 2016 was immaterial.

During the three and nine months ended September 30, 2017, the Company recorded a gain of $8 million and $9 million, respectively, in Other income (expense) for foreign exchange derivatives not designated or qualifying as hedges. During the three and nine months ended September 30, 2016, the Company recorded a gain of $2 million and $1 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 income (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 income (loss). Ineffective portions of net investment hedges, if any, are reclassified from Accumulated other comprehensive income (loss) into earnings during the period of change.

As of September 30, 2017, the Company had no outstanding Euro-denominated commercial paper designated as a hedge of the foreign currency exposure of its net investment in its European operations. As of September 30, 2017, the unrealized gain recognized in Accumulated other comprehensive income (loss) related to the net investment non derivative hedging instrument was immaterial.

The Company did not reclassify any deferred gains or losses related to net investment hedges from Accumulated other comprehensive income (loss) to earnings during the three and nine months ended September 30, 2017. In addition, the Company did not incur any ineffectiveness related to net investment hedges during the three and nine months ended September 30, 2017.

15. 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 Consolidated 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 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.

The following tables present the categorization of the Company’s assets and liabilities that are measured at fair value on a recurring basis at September 30, 2017 and December 31, 2016 (in millions):

16. 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 Consolidated Statements of Financial Position and have been recognized in Other general expenses in the 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 $0.3 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. The insurers have appealed both of these trial court decisions. 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 ($61 million at September 30, 2017 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 ($94 million at September 30, 2017 exchange rates). 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 ($133 million at September 30, 2017 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 ($381 million at September 30, 2017 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 Financial Conduct Authority (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, we 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 our consolidated financial position, results of operations, or liquidity.

Aon UK Limited, an indirect wholly-owned subsidiary of the Company, is presently engaged in several internal regulatory reviews and ongoing interactions with the FCA concerning Aon UK Limited’s systems and controls. These interactions may result in additional charges above amounts accrued for to date in connection with these reviews.

Settled/Closed Matters

On June 1, 2007, the International Road Transport Union (“IRU”) sued Aon in the Geneva Tribunal of First Instance in Switzerland. IRU alleges, among other things, that, between 1995 and 2004, a business acquired by Aon and, later, an Aon subsidiary (1) accepted commissions for certain insurance placements that violated a fee agreement entered between the parties and (2) negligently failed to ask certain insurance carriers to contribute to the IRU’s risk management costs. IRU sought damages of approximately CHF 46 million ($47 million at June 30, 2017 exchange rates) and $3 million, plus legal fees and interest of approximately $30 million. On December 2, 2014, the Geneva Tribunal of First Instance entered a judgment that accepted some, and rejected other, of IRU’s claims. The judgment awarded IRU CHF 16.8 million ($17 million at June 30, 2017 exchange rates) and $3.1 million, plus interest and adverse costs. The entire amount of the judgment, including interest through December 31, 2014, totaled CHF 27.9 million ($28 million at December 31, 2014 exchange rates) and $5 million. On January 26, 2015, in return for IRU agreeing not to appeal the bulk of its dismissed claims, the Aon subsidiary agreed not to appeal a part of the judgment and to pay IRU CHF 12.8 million ($14 million at January 31, 2015 exchange rates) and $4.7 million without Aon admitting liability. The Aon subsidiary appealed those aspects of the judgment it retained the right to appeal. IRU did not appeal. After the Geneva Appellate Court affirmed the judgment of the Geneva Tribunal of First Instance, the Aon subsidiary filed an appeal with the Swiss Federal Tribunal. By judgment issued June 16, 2017, the Swiss Federal Tribunal affirmed in part and reversed in part the appellate judgment and remanded the case to the appellate court. IRU and the Aon subsidiary agreed that the Aon subsidiary would pay IRU CHF 15.0 million ($15 million at June 30, 2017 exchange rates) and $344,000. As a result of this agreement, the legal proceedings between IRU and the Aon subsidiary have been discontinued.

Guarantees and Indemnifications

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.

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 Condensed Consolidated 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.

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 September 30, 2017, the undiscounted maximum potential future payments under the lease guarantee is $104 million, with an estimated fair value of $25 million. No cash payments were made in connection to the lease commitments during the three or nine months ended September 30, 2017.

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 September 30, 2017, the undiscounted maximum potential future payments under the performance guarantees were $395 million, with an estimated fair value of $4 million. No cash payments were made in connection to the performance guarantees during the three or nine months ended September 30, 2017.

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 $94 million at September 30, 2017, compared to $90 million at December 31, 2016. These letters of credit 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 $76 million at September 30, 2017 compared to $95 million at December 31, 2016.

17. Segment Information

Beginning in the first quarter of 2017 and following the Transaction described in Note 3 “Discontinued Operations,” the Company began 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. These initiatives reinforce Aon’s return on invested capital (“ROIC”) decision-making process and emphasis on free cash flow. The Company is now operating

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 CODM assesses the performance of the Company and allocates resources based on one company: 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.

Prior period comparative segment information has been restated to conform with current year presentation. In prior periods, the Company did not include unallocated expenses in segment operating income, which represented corporate governance costs not allocated to the previous operating segments. These costs are now reflected within operating expenses for the current and prior period.

Revenue from continuing operations for each of the Company’s principal product and service lines is as follows (in millions):



	Three months ended September 30						Nine months ended September 30
	2017			2016			2017			2016
Commercial Risk Solutions	$	917		$	884		$	2,943		$	2,835

Elimination	(5		)	(3		)	(9		)	(6		)
Total revenue	$	2,340		$	2,201		$	7,089		$	6,759

As Aon is operating as one segment, segment profit or loss is consistent with consolidated reporting as disclosed on the Condensed Consolidated Statements of Income.

The geographic distribution of Aon’s total revenue or long-lived assets did not change as a result of the change in reportable operating segments described above.

18. Guarantee of Registered Securities

As described in Note 16 “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 Corp 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 Corp 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 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 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”). In each case, the guarantee of Aon Corporation is 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.

The following tables set forth Condensed Consolidating Statements of Income for the three and nine months ended September 30, 2017 and 2016, Condensed Consolidating Statements of Comprehensive Income for the three and nine months ended September 30, 2017 and 2016, Condensed Consolidating Statements of Financial Position as of September 30, 2017 and December 31, 2016, and Condensed Consolidating Statements of Cash Flows for the nine months ended September 30, 2017 and 2016 in accordance with Rule 3-10 of Regulation S-X. The condensed consolidating financial information includes the accounts of Aon plc, the accounts of Aon Corporation, and the combined accounts of the non-guarantor subsidiaries. The condensed consolidating financial statements are presented in all periods as a merger under common control, with Aon plc presented as the parent company in all periods prior and subsequent to the Redomestication. The principal consolidating adjustments are to eliminate the investment in subsidiaries and intercompany balances and transactions.

As described in Note 1 “Basis of Presentation,” and consistent with the Company’s Condensed Consolidated Financial Statements, the following tables present the financial results of the Divested Business as discontinued operations for all periods presented within non-guarantor Subsidiaries. The impact of intercompany transactions have been reflected within continuing operations in the Condensed Consolidating Financial Statements.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

EXECUTIVE SUMMARY OF THIRD QUARTER 2017 FINANCIAL RESULTS

Aon is a leading global professional services firm providing a broad range of risk, retirement, and health solutions underpinned by proprietary data and analytics. Management 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. The divestiture of the benefits administration and business process outsourcing platform in Q2 2017 represents the next step of our strategy, which is consistent with our journey towards offering advice and solutions, and further aligning Aon’s portfolio around clients’ highest priorities. Further, it reinforces our ROIC decision-making process and emphasis on operating cash flow.

Discontinued Operations

On February 9, 2017, the Company entered into a Purchase Agreement with Tempo Acquisition, LLC to sell its benefits administration and business process outsourcing business to the Buyer, an entity formed and controlled by affiliates of The Blackstone Group L.P., 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 in each of the Divested Business’ subsidiaries, 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. Cash proceeds after customary adjustments and before taxes due were $4.2 billion.

In the nine months ended September 30, 2017, the Company recorded a gain on sale, net of taxes, of $803 million and a non-cash impairment charge to its tradenames associated with the Divested Business of $380 million as these assets were not sold to the Buyer. Additionally, effective May 1, 2017, consistent with operating as one segment, the Company has implemented a three-year strategy to transition to a unified Aon brand. As a result, Aon commenced amortization of all indefinite lived tradenames and prospectively accelerated amortization of its finite lived tradenames over the three-year period. The accelerated amortization and impairment charge are included in Amortization and impairment of intangible assets on the Condensed Consolidated Statement of Income.

Financial Results

The following is a summary of our third quarter and first nine months of 2017 financial results from continuing operations:

•

For the third quarter of 2017, revenue increased 6%, or $139 million, to $2.3 billion compared to the prior year period due primarily to a 3% increase related to acquisitions, net of divestitures, organic revenue growth of 2%, and a 1% favorable impact from foreign currency exchange rates. For the first nine months ended September 30, 2017, revenue increased 5% compared to the prior year period due primarily to organic revenue growth of 3% and a 3% increase related to acquisitions, net of divestitures, partially offset by a 1% unfavorable impact from foreign currency exchange rates.

•

Operating expenses for the third quarter of 2017 were $2.1 billion, an increase of $242 million compared to the prior year period. The increase was due primarily to $102 million of restructuring costs, a $62 million increase in operating expenses related to acquisitions, net of divestitures, $54 million of accelerated amortization related to tradenames, a $16 million unfavorable impact from foreign currency translation, $10 million of transaction related costs associated with recent acquisitions, and an increase in expense associated with 2% organic revenue growth, partially offset by $55 million of savings related to restructuring and other operational improvement initiatives. Operating expenses for the first nine months of 2017 increased $1,015 million compared to the prior year period primarily due to $401 million of restructuring costs, a $380 million non-cash impairment charge to the tradenames associated with the Divested Business, a $183 million

increase in operating expenses related to acquisitions, net of divestitures, $89 million of accelerated amortization related to tradenames to move to the one Aon United brand, $42 million of costs related to regulatory and compliance matters, and an increase in expense associated with organic revenue growth of 3%, partially offset by $109 million of savings related to restructuring and other operational improvement initiatives, a $76 million favorable impact from foreign currency exchange rates, and $62 million of expense related to certain non-cash pension settlements in the prior year period.

•

Operating margin decreased to 11.3% in the third quarter of 2017 from 16.7% in the prior year period. The decrease was driven by an increase in expense due to the factors listed above, partially offset by organic revenue growth of 2%. The decrease from the prior year period and first nine months of 2017 was driven by an increase in expense due to the factors listed above, partially offset by organic revenue growth of 3%.


•	Due to the factors set forth above, income from continuing operations decreased $88 million, or 31%, to $196 million for the third quarter of 2017 compared to the prior year period. During the first nine months of 2017, income from continuing operations decreased $451 million, or 52%, to $418 million compared to the first nine months of 2016.


•	Cash flow provided by operating activities was $289 million for the first nine months of 2017, a decrease of $863 million from $1,152 million in the prior year period. The decrease was driven primarily by cash tax payments associated with the Divested Business and $199 million of 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 Condensed Consolidated Financial Statements and Notes thereto. The following is our measure of performance against these four metrics from continuing operations for the third quarter of 2017:


•	Organic revenue growth, a non-GAAP measure defined under the caption “Review of Consolidated Results — Organic Revenue Growth,” was 2% for the third quarter of 2017, compared to 4% organic growth in the prior year period. Organic revenue growth was 3% for the first nine months of 2017, compared to 3% in the prior year period.

•

Adjusted operating margin, a non-GAAP measure defined under the caption “Review of Consolidated Results — Adjusted Operating Margin,” was 20.3% for the third quarter of 2017 compared to 18.6% for the prior year period. For the first nine months of 2017, adjusted operating margin was 21.7% as compared to 20.0% for the prior year period. The increases primarily reflect restructuring savings, organic revenue growth, and underlying operational improvement, partially offset by expenses related to reinvestment.


•	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 $1.29 per share for the third quarter of 2017 and $4.19 in the first nine months of 2017, compared to $1.09 per share and $3.59 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 nine months of 2017 by $881 million, or 84% from the prior year period, to $164 million, driven by a decrease of $863 million in cash flow from operations and an increase of $18 million in capital expenditures, including investments in our operating model.

Compensation and Benefits

Compensation and benefits increased $119 million, or 9%, in the third quarter of 2017 compared to the third quarter of 2016. This increase was primarily driven by $52 million of restructuring costs, a $37 million increase in expenses from businesses acquired, net of divestitures, a $14 million unfavorable impact from foreign currency translation, $2 million of transaction related costs associated with recent acquisitions, and an increase in expense associated with 2% organic revenue growth, partially offset by $32 million of savings related to restructuring and other operational improvement initiatives. For the first nine months of 2017, compensation and benefits increased $296 million, or 7%, compared to the first nine months of 2016. The increase was primarily driven by $257 million of restructuring costs, a $110 million increase in expenses related to acquisitions, net of divestitures, and an increase in expense associated with 3% organic revenue growth, partially offset by $62 million of expense related to certain non-cash pension settlements in the prior year period, $62 million of savings related to restructuring and other operational improvement initiatives, and a $53 million favorable impact from foreign currency translation.

Information Technology

Information technology, which represents costs associated with supporting and maintaining our infrastructure, increased $10 million, or 10%, in the third quarter of 2017 compared to the third quarter of 2016. This increase was primarily driven by $12 million of restructuring costs, as well as investments in growth, partially offset by $13 million of savings related to restructuring and other operational improvement initiatives. For the first nine months of 2017, information technology increased $14 million, or 5%, compared to the prior year period. This increase was primarily driven by $22 million of restructuring charges and investments in growth, partially offset by $29 million of savings related to restructuring and other operational improvement initiatives.

Premises

Premises, which represents the cost of occupying offices in various locations throughout the world, increased $3 million, or 3%, in the third quarter of 2017 compared to the third quarter of 2016. This increase was primarily driven by $4 million of restructuring costs, partially offset by $1 million of savings related to restructuring and other operational improvement initiatives. For the first nine months of 2017, premises increased $2 million, or 1%, compared to the first nine months of 2016. This increase was primarily driven by a $9 million increase in expenses related to acquisitions, net of divestitures and $8 million of restructuring costs, partially offset by $2 million of savings related to restructuring and other operational improvement initiatives and a decrease in expense as we optimize our real estate footprint.

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 increased $1 million, or 3%, in the third quarter of 2017 compared to the third quarter of 2016. This increase was primarily driven by $2 million of restructuring costs. For the first nine months of 2017, depreciation of fixed assets increased $30 million, or 25%, compared to the first nine months of 2016. This increase was primarily driven by $26 million of restructuring costs and a $12 million increase in expenses related to acquisitions, net of divestitures.

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 increased $59 million, or 140%, in the third quarter of 2017 compared to the third quarter of 2016 due to $54 million of accelerated amortization related to tradenames. For the first nine months of 2017, amortization and impairment of intangibles increased $487 million, or 416%, compared to the first nine months of 2016 due to a $380 million non-cash impairment charge to the tradenames associated with the sale of the Divested Business and $89 million of accelerated amortization related to tradenames.

Other General Expenses

Other general expenses in the third quarter of 2017 increased $50 million, or 19%, compared to the third quarter of 2016. This increase was due primarily to $32 million of restructuring costs, a $17 million increase in operating expenses related to acquisitions, net of divestitures, $8 million of costs related to regulatory and compliance matters, and $8 million of transaction related costs associated to recent acquisitions, partially offset by $9 million of savings from restructuring and other operational improvement initiatives. For the first nine months of 2017, other general expenses increased $186 million, or 24%, compared to the prior year period. This increase was primarily driven by $88 million of restructuring costs, a $49 million increase in operating expenses related to acquisitions, net of divestitures, $42 million of costs related to regulatory and compliance matters, and an increase in expense associated with 3% organic revenue growth, partially offset by $16 million of savings related to restructuring and other operational improvement initiatives and a $13 million favorable impact from foreign currency translation.

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 third quarter of 2017, Interest income was $10 million, compared to $1 million during the prior year period. For the first nine months of 2017, Interest income was $20 million, compared to $6 million during the prior year period. The increase in both periods reflects additional income earned on the proceeds from the sale of the Divested Business.

Interest Expense

Interest expense, which represents the cost of our debt obligations, was $70 million during the third quarter of 2017, similar to $70 million for the prior year period. For the first nine months of 2017, Interest expense was $211 million, a decrease from $212 million for the prior year period.

Other Income (Expense)

Other expense was $5 million for the third quarter of 2017, compared to other income of $10 million for the third quarter of 2016. Other expense for the third quarter of 2017 primarily includes $20 million of losses due to the unfavorable impact of exchange rates on the remeasurement of assets and liabilities in non-functional currencies, partially offset by $16 million of gains on financial instruments. Other income of $10 million in the third quarter of 2016 primarily includes gains on certain long term investments.

Other expense was $20 million for the first nine months of 2017, compared to other income of $27 million for the prior year period. Other expense for the first nine months of 2017 primarily includes $32 million of losses due to the unfavorable impact of exchange rates on the remeasurement of assets and liabilities in non-functional currencies, excluding hedging gains, partially offset by $6 million of gains on certain financial instruments. Other income of $27 million in the first nine months of 2016 primarily included $41 million of net gains on the sale of certain businesses, partially offset by a $14 million unfavorable impact of exchange rates on the remeasurement of assets and liabilities in non-functional currencies, excluding hedging losses.

Income From Continuing Operations before Income Taxes

Due to the factors discussed above, income from continuing operations before income taxes for the third quarter of 2017 was $200 million, a 35% decrease from $309 million in the third quarter of 2016, and $279 million for the first nine months of 2017, a 72% decrease from $996 million in the first nine months of 2016.

Income Taxes From Continuing Operations

The effective tax rate on net income from continuing operations was 2.0% and 8.1% for the third quarters of 2017 and 2016, respectively. The effective tax rate on net income from continuing operations was (49.8)% and 12.8% for the nine months ended September 30, 2017 and 2016, respectively. For the nine months ended September 30, 2017, the Company reported a tax benefit of $139 million on pretax income of $279 million, which resulted in an effective tax rate of (49.8)%. The primary components of this tax amount were the non-cash tax benefit from the tradename impairment associated with the Divested Business and the impact of share-based payments from adoption of the new share-based compensation guidance.

Income from Discontinued Operations, Net of Tax

On February 9, 2017, the Company entered into the Purchase Agreement with Tempo Acquisition, LLC to sell the Divested Business. The Company has retrospectively classified the results of the Divested Business as discontinued operations in the Company’s Condensed Consolidated Statements of Income for all periods presented. Income from discontinued operations, net of tax, decreased $46 million in the third quarter of 2017 as compared to the prior year period. The decrease was primarily driven by run off expenses associated with the Divested Business. Income from discontinued operations, net of tax, increased $755 million in the first nine months of 2017 as compared to the prior year period. The increase is primarily driven by a $803 million gain on sale of the Divested Business.

Net Income Attributable to Aon Shareholders

Net income attributable to Aon shareholders for the three months ended September 30, 2017 decreased to $185 million, or $0.72 per diluted share, from $319 million, or $1.18 per diluted share, in the prior year period. Net income attributable to Aon shareholders for the first nine months of 2017 increased to $1,245 million, or $4.74 per diluted share, from $944 million, or $3.48 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 Condensed Consolidated Financial Statements and Notes thereto.

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 changes in foreign exchange rate, acquisitions, divestitures, transfers between subsidiaries, fiduciary investment income, and reimbursable expenses. 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 Condensed Consolidated Financial Statements and Notes thereto. Industry peers provide similar supplemental information about their revenue performance, although they may not make identical adjustments.

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 Condensed Consolidated Financial Statements and Notes thereto.

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 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 Condensed Consolidated Financial Statements and Notes thereto.

The effective tax rates used in the U.S. GAAP financial statements for continuing operations were 2.0% and (49.8)%, respectively, for the three and nine months ended September 30, 2017. Adjusted items are generally taxed at the estimated annual effective tax rate, except for the applicable tax impact associated with estimated restructuring expenses, accelerated tradename amortization, impairment charges, regulatory and compliance provisions, and non-cash pension settlement charges anticipated in the forth quarter of 2017, which are adjusted at the related jurisdictional rate. After adjusting to exclude the applicable tax impact, the adjusted effective tax rates for continuing operations were 17.5% and 14.6%, respectively, for the three and nine months ended September 30, 2017. The effective tax rates used in the U.S. GAAP financial statements for continuing operations were 8.1% and 12.8%, respectively, for the three and nine months ended 2016. Adjusted items are generally taxed at the estimated annual effective tax rate, except for the applicable tax impact associated with non-cash pension charges settled in the second quarter of 2016, which are adjusted at the related jurisdictional rate. After adjusting to exclude the applicable tax impact, the adjusted effective tax rates for continuing operations were 14.2% and 15.0%, respectively, for the three and nine months ended 2016.

Adjusted income from discontinued operations, net of tax, excludes the gain on sale and intangible asset amortization on discontinued operations of $11 million and $0 million, respectively, for the three months ended September 30, 2017 and $1,983 million and $11 million for the nine months ended September 30, 2017. The effective tax rates used in the U.S. GAAP financial statements for discontinued operation were 35.1% and 21.8%, respectively, for the three months and nine months ended September 30, 2017. After adjusting to exclude the applicable tax impact associated with the gain on sale and intangible asset amortization, the adjusted effective tax rates for discontinued operations were 35.2% and 24.2%, respectively, for the three months and nine months ended September 30, 2017. Adjusted income from discontinued operations, net of tax, excludes intangible asset amortization on discontinued operations of $30 million and $90 million, respectively, for the three months and nine months ended September 30, 2016. The effective tax rates used in the U.S. GAAP financial statements for discontinued operation were 37.3% and 37.4% for the three and nine months ended 2016, respectively. After adjusting to exclude the applicable tax impact associated with amortization, the adjusted effective tax rates for discontinued operations were 32.8% and 32.4% for the three and nine months ended 2016, respectively.

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 Condensed Consolidated Financial Statements and Notes thereto. 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, except percentages):



	Nine Months Ended
	September 30, 2017			September 30, 2016
Cash Provided by Continuing Operating Activities	$	289		$	1,152
Capital Expenditures Used for Continuing Operations	(125		)	(107		)
Free Cash Flow Provided By Continuing Operations	$	164		$	1,045

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 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 $0.01 and $0.06 impacts, respectively, on net income per diluted share during the three and nine months ended September 30, 2017. Currency fluctuations had $0.03 and $(0.03) impacts, respectively, on net income per diluted share during the three and nine months ended September 30, 2016, when 2015 results were translated at 2016 rates.

Translating prior year quarter results at current quarter foreign exchange rates, currency fluctuations had $0.01 and $0.02 impacts, respectively, on adjusted net income per diluted share during the three and nine months ended September 30, 2017. Currency fluctuations had $0.02 and $(0.07) impacts, respectively, on adjusted net income per diluted share during the three and nine months ended September 30, 2016, when 2015 results were translated at 2016 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 Condensed Consolidated Financial Statements.

Restructuring Plan

In 2017, we 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. We expect these restructuring activities and related expenses to affect continuing operations through 2019, including an estimated 2,400 to 2,850 role eliminations. The Restructuring Plan is expected to result in cumulative costs of approximately $750 million through the end of the plan, consisting of approximately $303 million in employee termination costs, $146 million in technology rationalization costs, $80 million in real estate consolidation costs, $40 million in asset impairments and $181 million in other costs including certain separation costs associated with the sale of the Divested Business. Included in the estimated $750 million is $50 million of estimated non-cash charges related to asset impairments and lease consolidations. We estimate that our annualized savings from the Restructuring Plan will be approximately $400 million by the end of 2019.

From the inception of the Restructuring Plan through September 30, 2017, the Company has eliminated 2,125 positions and a total of $401 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 September 30, 2017 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 September 30, 2017		Nine months ended September 30, 2017		Estimated Remaining Costs		Estimated Total Cost ⁽¹⁾
Workforce reduction	$	52	$	257	$	46	$	303

Total restructuring and related expenses	$	102	$	401	$	349	$	750

Actual costs, when incurred, may vary due to changes in the assumptions built into this 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.

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 has indicated that it will assess whether any feature or combination of features in the target market prevents, restricts, or distorts competition. The CMA can impose a wide range of remedies to address uncompetitive markets. The investigation is in its very early stages. Thus, we are not presently in a position to estimate the impact, if any, of this investigation on Aon’s UK investment business.

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 flow from operations, available cash reserves, and debt capacity available under our credit facility. Our primary uses of liquidity are operating expenses, 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. Fiduciary funds generally cannot be used for general corporate purposes, and are not a source of liquidity for us.

Operating Activities

Net cash provided by operating activities during the nine months ended September 30, 2017 decreased $1,122 million, or 76%, to $353 million from the prior year period. Net cash provided by operating activities for continuing operations during the nine months ended September 30, 2017 decreased $863 million, or 75%, from the prior year period to $289 million. Net cash provided by operating activities for discontinued operations during the nine months ended September 30, 2017 decreased $259 million, or 80%, from the prior year period to $64 million. These amounts represent net income reported, as adjusted for gains or losses on sales of businesses, financial instruments and foreign exchange, and our non-cash expenses, which include share-based compensation, depreciation, and amortization and impairments, 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. The total decrease in operating cash inflows from the prior year was primarily driven by higher cash tax charges, largely related to the sale of the Divested Business, and an increase in pension contributions.

Pension contributions were $109 million for the nine months ended September 30, 2017, as compared to $91 million for the nine months ended September 30, 2016. For the remainder of 2017, we expect to contribute approximately $40 million in cash to our pension plans, with the majority attributable to non-U.S. pension plans, which are subject to changes in foreign exchange rates. On July 1, 2017, the Company made non-cash contributions of approximately $80 million to its U.S. pension plan.

We expect cash generated by operations for 2017 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 facility to accommodate any timing differences in cash flows. We have a committed credit facility totaling $900 million, all of which was available at September 30, 2017, and can access this facility on a same day or next day basis. In October 2017, we entered into a $400 million multi-currency U.S. credit facility, which increases our available facilities to $1.3 billion. Additionally, under current market conditions, we believe that we could access capital markets to obtain debt financing for longer-term funding, if needed.

Investing Activities

Cash flow provided by investing activities was $2,522 million during the nine months ended September 30, 2017. During the nine months ended September 30, 2017, cash flow provided by investing activities in continuing operations was $2,541 million and cash flow used for investing activities in discontinued operations was $19 million. The primary driver of cash flow provided by investing activities was $4,194 million of sales of businesses, net of cash sold, offset by $1,344 million in net purchases of short-term investments, $172 million of acquisitions of businesses, net of cash acquired, and $144 million of capital expenditures in continuing and discontinued operations, and $12 million of net purchases of long-term investments. The gains and losses corresponding to cash flows provided by the net sales of long-term investments are recognized in Other income (expense) in the Condensed Consolidated Statements of Income.

Cash flow used for investing activities was $371 million during the nine months ended September 30, 2016. During the nine months ended September 30, 2016, cash flow used for investing activities in continuing operations was $325 million and cash flow used for investing activities in discontinued operations was $46 million. The primary drivers of cash flow used for investing activities were $198 million of acquisitions of businesses, net of cash acquired, $153 million of capital expenditures in continuing and discontinued operations, $108 million in net purchases of short-term investments, and $16 million of net purchases of long-term investments, offset by $104 million in proceeds from the sale of businesses.

Financing Activities

Cash flow used for financing activities during the nine months ended September 30, 2017 was $2,648 million, all of which was related to continuing operations. The primary drivers of cash flow used for financing activities were $1,888 million of share repurchases, $347 million of repayments of debt, net of issuances, $274 million of dividends paid to shareholders, $118 million in net cash payments related to issuance of shares, and $21 million of transactions with noncontrolling interests and other financing activities.

Cash flow used for financing activities during the nine months ended September 30, 2016 was $1,015 million, all of which was related to continuing operations. The primary drivers of cash flow used for financing activities were $1,037 million of share repurchases, $258 million of dividends paid to shareholders, $71 million of transactions with noncontrolling interests and other

financing activities, and $70 million in net cash payments related to issuance of shares, partially offset by $421 million of issuances of debt, net of repayments.

Cash and Cash Equivalents and Short-Term Investments

At September 30, 2017, our Cash and cash equivalents and Short-term investments were $2,389 million, an increase of $1,673 million from December 31, 2016. This increase was primarily related to $4,194 million received in connection with the Divested Business and $353 million cash provided by operations, partially offset by $1,888 million in share repurchases, $347 million in repayments of debt issuances, net of issuances, $274 million in dividends, $172 million in acquisitions of businesses, net of cash acquired, and $144 million of capital expenditures. Of the total balance at September 30, 2017, $98 million was restricted as to its use, which was comprised of £42.7 million ($57.5 million at September 30, 2017 exchange rates) of operating funds in the U.K., as required by the FCA, and $40 million held as collateral for various business purposes. At September 30, 2017, $4.7 billion of Cash and cash equivalents and Short-term investments were held in the U.S. and overdrawn Cash and cash equivalents and Short-term investments of $2.3 billion were held in other countries. 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 September 30, 2017, non-U.S. cash balances of one or more entities were negative; however, the overall balance was positive.

Of the total balance of Cash and cash equivalents and Short-term investments at December 31, 2016, $82 million was restricted as to its use, which was comprised of £43.3 million ($53.2 million at December 31, 2016 exchange rates) of operating funds in the U.K., as required by the FCA, and $29 million held as collateral for various business purposes. At December 31, 2016, $1.9 billion of cash and cash equivalents and short-term investments were held in the U.S. and overdrawn Cash and cash equivalents and Short-term investments of $1.2 billion were held in other countries.

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. Our Fiduciary assets included cash and short-term investments of $4.2 billion and $3.3 billion at September 30, 2017 and December 31, 2016, respectively, and fiduciary receivables of $5.0 billion and $5.7 billion at September 30, 2017 and December 31, 2016, 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.

As disclosed in Note 15 “Fair Value Measurements and Financial Instruments” of Notes to the Condensed Consolidated 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.

At September 30, 2017, our investments in money market funds had a fair value of $3.1 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 at September 30, 2017 (in millions):

Share Repurchase Program

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, based on prevailing market conditions, and will be funded from available capital. In the three months ended September 30, 2017, the Company repurchased 5.4 million shares at an average price per share of $139.61, for a total cost of approximately $749 million and recorded an additional $3.8 million of costs associated with the repurchases to retained earnings. During the nine months ended September 30, 2017, the Company repurchased 14.5 million shares at an average price per share of $131.58, for a total cost of approximately $1.9 billion and recorded an additional $9.5 million of costs associated with the repurchases to retained earnings. Included in the 5.4 million shares and 14.5 million shares repurchased during the three and nine months ended September 30, 2017 were 165 thousand shares that did not settle until October 2017. These shares were settled at an average price per share of $146.52 and total cost of $24.2 million. In the three months ended September 30, 2016, the Company repurchased 2.7 million shares at an average price per share of $110.26 for a total cost of approximately $301 million. During the nine months ended September 30, 2016, the Company repurchased 10.4 million shares at an average price per share of $101.16, for a total cost of approximately $1.1 billion.

At September 30, 2017, the remaining authorized amount for share repurchase under the Repurchase Program is approximately $5.9 billion. Under the Repurchase Program, we have repurchased a total of 104.7 million shares for an aggregate cost of approximately $9.1 billion.

For information regarding share repurchases made during the third quarter of 2017, see Part II, Item 2 of this report.

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 September 30, 2017 and December 31, 2016, we had distributable reserves in excess of $1.8 billion and $1.6 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.

Borrowings

Total debt at September 30, 2017 was $6.0 billion, a decrease of $238 million compared to December 31, 2016. Commercial paper activity during the three and nine months ended September 30, 2017 and 2016 is as follows:



	Three Months Ended					Nine Months Ended
	September 30, 2017		September 30, 2016			September 30, 2017			September 30, 2016
Total Issuances	$	—	$	674		$	1,648		$	1,982
Total Repayments	$	—	$	(674	)	$	(1,997	)	$	(1,798	)

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

Credit Facilities

As of September 30, 2017, Aon plc had one primary committed credit facility outstanding: its $900 million multi-currency U.S. credit facility expiring in February 2021 (the “2021 Facility”). On October 19, 2017, Aon entered into a $400 million multi-currency U.S. credit facility expiring in October 2022 (the “2022 Facility”). This facility replaced the previous $400 million U.S. credit facility that expired in March 2017. The 2021 facility is intended to support our commercial paper obligations and our general working capital needs. In addition, this facility 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 adjusted consolidated EBITDA, tested quarterly. During the second quarter of 2017, Aon amended the consolidated EBITDA definition within our 2021 Facility to exclude non-cash pension expenses and restructuring charges, not to exceed the total estimated costs of $750 million. At September 30, 2017, we had no borrowings under, and were in compliance with, these financial covenants and all other covenants contained in the 2021 Facility during the three and nine months ended September 30, 2017.

Our total debt-to-EBITDA ratio at September 30, 2017 and 2016 based on a rolling twelve months is calculated as follows (in millions):



	Rolling twelve months ended
	September 30,
	2017			2016
Net income	$	802		$	1,322
Interest expense	281			280
Income taxes	(118		)	192
Depreciation of fixed assets	192			161
Amortization and impairment of intangible assets	644			159
Restructuring charges	375			—
Non-cash pension expense	128			31
Total EBITDA	$	2,304		$	2,145
Total Debt	$	5,967		$	6,160
Total debt-to-EBITDA ratio	2.6			2.9

The debt-to-EBITDA ratio was retrospectively restated to exclude the impact of discontinued operations related to the sale of the Divested Business. Refer to Note 3 “Discontinued Operations” of Notes to Condensed Consolidated Financial Statements for further information.

We use EBITDA for continuing operations, as defined by our financial covenants, as a non-GAAP measure. This supplemental information related to EBITDA represents a measure not in accordance with U.S. GAAP and should be viewed in addition to, not instead of, our Condensed Consolidated Financial Statements and Notes thereto.

Shelf Registration Statement

On September 3, 2015, we filed a shelf registration statement with the U.S. Securities and Exchange Commission (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 October 27, 2017 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 and commercial paper could increase our borrowing costs, reduce or eliminate our access to capital, reduce our financial flexibility, increase our commercial paper interest rates, or restrict our access to the commercial paper market altogether, and/or impact future pension contribution requirements.

Guarantees and Indemnifications

Sale of the Divested Business

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 September 30, 2017, the undiscounted maximum potential future payments under the lease guarantee were $104 million, with an estimated fair value of $25 million. No cash payments were made in connection to the lease commitments during the three or nine months ended September 30, 2017.

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 September 30, 2017, the undiscounted maximum potential future payments under the performance guarantees were $395 million, with an estimated fair value of $4 million. No cash payments were made in connection to the performance guarantees during the three or nine months ended September 30, 2017.

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 (“LOCs”). We had total LOCs outstanding of approximately $94 million at September 30, 2017, compared to $90 million at December 31, 2016. 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 $76 million at September 30, 2017, compared to $95 million at December 31, 2016.

Other Liquidity Matters

We do not have significant exposure related to off-balance sheet arrangements. Our cash flows from operations, borrowing availability, and overall liquidity are subject to risks and uncertainties. See “Information Concerning Forward-Looking Statements” below.

Financial Condition

At September 30, 2017, our net assets, representing total assets minus total liabilities, were $5,247 million, a decrease from $5,532 million at December 31, 2016. The decrease was due primarily to $1,913 million of share repurchases and $274 million of dividend payments for the nine months ended September 30, 2017, partially offset by Net income of $1,275 million, a decrease of $500 million in Accumulated other comprehensive loss, and an increase of $49 million due to the adoption of the share-based compensation guidance in the first quarter of 2017. Working capital increased by $1,142 million to $1,793 million from December 31, 2016.

Accumulated Other Comprehensive Loss

Accumulated other comprehensive loss decreased $500 million to $3,412 million at September 30, 2017 as compared to $3,912 million at December 31, 2016, which was primarily driven by the following:


•	positive net foreign currency translation adjustments of $431 million, which are attributable to the weakening of the U.S. dollar against certain foreign currencies;


•	an increase of $56 million due to the amortization of net actuarial losses related to pension obligations; and


•	net financial instrument gains of $13 million.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

There have been no changes in our critical accounting policies, which include revenue recognition, 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, 2016 ( our “2016 Annual Report on Form 10-K”) other than those described below.

Restructuring

Workforce reduction costs

The method used to account for workforce reduction costs depends on whether the costs result from an ongoing severance plan or are one-time costs. We account for relevant expenses as severance costs when we have an established severance policy, statutory requirements dictate the severance amounts, or we have an established pattern of paying by a specific formula. We recognize these costs when the likelihood of future settlement is probable and the amount of the related benefit is reasonably estimable, or on a straight-line basis over the remaining service period, if applicable.

We estimate our one-time workforce reduction costs related to exit and disposal activities not resulting from an ongoing severance plan based on the benefits available to the employees being terminated. We recognize these costs when we identify the specific classification (or functions) and locations of the employees being terminated, notify the employees who might be included in the termination, and expect to terminate employees within the legally required notification period. When employees are receiving incentives to stay beyond the legally required notification period, we record the cost of their severance over the remaining service period.

Lease consolidation costs

Where we have provided notice of cancellation pursuant to a lease agreement or abandoned space and have no intention of reoccupying it, we recognize a loss. The loss reflects our best estimate of the net present value of the future cash flows associated with the lease at the date we provide notice of cancellation in accordance with contractual terms, vacate the property, or sign a sublease arrangement. To determine the loss, we estimate sublease income based on current market quotes for similar properties. When we finalize definitive agreements with the sublessee, we adjust our sublease losses for actual outcomes.

Fair value concepts of one-time workforce reduction costs and lease losses

Accounting guidance requires that our exit and disposal accruals reflect the fair value of the liability. Where material, we discount the lease loss calculations to arrive at their net present value. Most workforce reductions happen over a short span of time, so no discounting is necessary.

For the remaining lease term, we decrease the liability for payments and increase the liability for accretion of the discount, if material. The discount reflects our incremental borrowing rate, which matches the lifetime of the liability. Significant changes in the discount rate selected or the estimations of sublease income in the case of leases could impact the amounts recorded.

Asset impairments

Asset impairments are accounted for in the period when they become known. Furthermore, we record impairments by reducing the book value to the net present value of future cash flows (in situations where the asset had an identifiable cash flow stream) or accelerating the depreciation to reflect the revised useful life. Asset impairments are included in Depreciation in the Condensed Consolidated Statements of Income.

Other associated costs of exit and disposal activities

We recognize other costs associated with exit and disposal activities as they are incurred, including separation costs, moving costs and consulting and legal fees.

NEW ACCOUNTING PRONOUNCEMENTS

Note 2 “Accounting Principles and Practices” to the Condensed Consolidated 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;


•	the level of our debt limiting financial flexibility or increasing borrowing costs;


•	rating agency actions that could affect our ability to borrow funds;


•	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 investments and other advisory services and business process outsourcing services, among others, that we currently provide, or will provide in the future, to clients;


•	our ability to continue, and the costs 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 of the Divested Business; and


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

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, 2016. 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 2016 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 September 30, 2017, 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, 2017 and 2018, respectively. We generally do not hedge exposures beyond three years.

We also use forward 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 increase by $0.01 and $0.06, respectively, during the three and nine months ended September 30, 2017. 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 increase by $0.01 and $0.02, respectively, during the three and nine months ended September 30, 2017 if we were to translate prior year results at current quarter exchange rates.

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 September 30, 2017. 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 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 September 30, 2017 that have materially affected, or that are reasonably likely to materially affect, Aon’s internal control over financial reporting.

Part II Other Information

Item 1. Legal Proceedings

See Note 16 “Commitments and Contingencies — Legal” to the Condensed Consolidated Financial Statements contained in Part I, Item 1 of this report, which is incorporated by reference herein.

Item 1A. Risk Factors

The risk factors set forth in Part I, “Item 1A. Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2016 reflect certain risks associated with existing and potential lines of business and contain “forward-looking statements” as discussed in Part I, Item 2 of this report. Readers should consider them in addition to the other information contained in this report as our business, financial condition or results of operations could be adversely affected if any of these risks actually occur.

Except as otherwise described below, there were no material changes to the risk factors previously disclosed in our 2016 Annual Report on Form 10-K.

We have added the risk factor “We may not realize all of the expected benefits from our restructuring plan.”

We have replaced the risk factor, “We are subject to various risks and uncertainties in connection with the pending sale of our Benefits and Administration and HR Business Process Outsourcing (BPO) Platform” with “We are subject to various risks and uncertainties in connection with the sale of our Benefits Administration and HR Business Process Outsourcing business.”

We may not realize all of the expected benefits from our restructuring plan.

In 2017, we initiated a global restructuring plan (the “Restructuring Plan”) in connection with the sale of our benefits administration and business process outsourcing 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 2,400 to 2,850 role eliminations. The Restructuring Plan is expected to result in cumulative costs of approximately $750 million through the end of the Restructuring Plan, consisting of approximately $303 million in employee termination costs, $146 million in IT rationalization costs, $80 million in real estate realization costs, $40 million in asset impairment costs, and $181 million in other costs associated with the restructuring. Included in the estimated $750 million is $50 million of estimated non-cash charges related to asset impairments and lease consolidations.

We estimate that our annualized savings from the Restructuring Plan will be approximately $400 million by the end of 2019. Actual total costs, savings and timing of the Restructuring Plan may vary from these estimates due to changes in the scope or assumptions underlying the Restructuring Plan. We therefore cannot assure that we will achieve the targeted savings. Unanticipated costs or unrealized savings in connection with the Restructuring Plan could adversely affect our results of operations and financial condition.

We are subject to various risks and uncertainties in connection with the sale of our Benefits Administration and HR Business Process Outsourcing business.

On February 9, 2017, we entered into a Purchase Agreement with Tempo Acquisition, LLC to sell our benefits administration and business process outsourcing business to the Buyer, an entity controlled by affiliates of The Blackstone Group L.P. On May 1, 2017, the transaction was consummated and the Buyer purchased all of the outstanding equity interests in each of the Divested Business’s subsidiaries, plus certain related assets, for a purchase price of (i) $4.3 billion in cash paid at closing, subject to customary adjustments set forth in the Purchase Agreement, and (ii) deferred consideration of up to $500 million, plus the assumption of certain liabilities.

The Transaction carries inherent risks, including the risk that Aon will not earn the $500 million of additional consideration or otherwise realize the intended value of the Transaction, as well as risks connected with separating the Divested Business from Aon. Because the Divested Business represented 19% of our gross revenues for the fiscal year 2016, our results of operations and financial condition may be materially adversely affected, or may not be accretive to adjusted earnings per share as anticipated, if we fail to effectively reduce our overhead costs to reflect the reduced scale of operations or fail to grow our other business as expected. Additionally, the separation of the Divested Businesses from the rest of Aon’s business will require significant resources, which may disrupt operations or divert management’s attention from Aon’s day-today operations and efforts to grow our other businesses.

Furthermore, we have entered into ongoing commercial arrangements with the Buyer. If we do not realize the intended benefits of these arrangements, it could affect our results of operations or adversely affect our relationship with clients, partners, colleagues

and other third parties. Additionally, if the Divested Business does not deliver the level of service to which our clients and partners are accustomed, it could adversely affect our relationships with such third parties.

(2)

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. During the third quarter of 2017, we repurchased 5.4 million shares at an average price per share of $139.61 for a total cost of $749 million. Included in the 5.4 million shares repurchased was 165 thousand shares, which are included in the above table, that did not settle until October 2017. These shares were settled at an average price per share of $146.52 and total cost of $24.2 million.

We did not make any unregistered sales of equity in the third quarter of 2017.
